# Reply by email
GitLab can be set up to allow users to comment on issues and merge requests by
replying to notification emails.
## Requirement
Reply by email requires an IMAP-enabled email account. GitLab allows you to use
three strategies for this feature:
- using email sub-addressing
- using a dedicated email address
- using a catch-all mailbox
### Email sub-addressing
**If your provider or server supports email sub-addressing, we recommend using it.**
[Sub-addressing](https://en.wikipedia.org/wiki/Email_address#Sub-addressing) is
a feature where any email to `user+some_arbitrary_tag@example.com` will end up
in the mailbox for `user@example.com`, and is supported by providers such as
Gmail, Google Apps, Yahoo! Mail, Outlook.com and iCloud, as well as the Postfix
mail server which you can run on-premises.
### Dedicated email address
This solution is really simple to set up: you just have to create an email
address dedicated to receive your users' replies to GitLab notifications.
### Catch-all mailbox
A [catch-all mailbox](https://en.wikipedia.org/wiki/Catch-all) for a domain will
"catch all" the emails addressed to the domain that do not exist in the mail
server.
## How it works?
### 1. GitLab sends a notification email
When GitLab sends a notification and Reply by email is enabled, the `Reply-To`
header is set to the address defined in your GitLab configuration, with the
`%{key}` placeholder (if present) replaced by a specific "reply key". In
addition, this "reply key" is also added to the `References` header.
### 2. You reply to the notification email
When you reply to the notification email, your email client will:
- send the email to the `Reply-To` address it got from the notification email
- set the `In-Reply-To` header to the value of the `Message-ID` header from the
notification email
- set the `References` header to the value of the `Message-ID` plus the value of
the notification email's `References` header.
### 3. GitLab receives your reply to the notification email
When GitLab receives your reply, it will look for the "reply key" in the
following headers, in this order:
1. the `To` header
1. the `References` header
If it finds a reply key, it will be able to leave your reply as a comment on
the entity the notification was about (issue, merge request, commit...).
For more details about the `Message-ID`, `In-Reply-To`, and `References headers`,
please consult [RFC 5322](https://tools.ietf.org/html/rfc5322#section-3.6.4).
## Set it up
If you want to use Gmail / Google Apps with Reply by email, make sure you have
[IMAP access enabled](https://support.google.com/mail/troubleshooter/1668960?hl=en#ts=1665018)
and [allowed less secure apps to access the account](https://support.google.com/accounts/answer/6010255).
To set up a basic Postfix mail server with IMAP access on Ubuntu, follow
[these instructions](./postfix.md).
### Omnibus package installations
1. Find the `incoming_email` section in `/etc/gitlab/gitlab.rb`, enable the
feature and fill in the details for your specific IMAP server and email account:
```ruby
# Configuration for Postfix mail server, assumes mailbox incoming@gitlab.example.com
gitlab_rails['incoming_email_enabled'] = true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
gitlab_rails['incoming_email_address'] = "incoming+%{key}@gitlab.example.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
gitlab_rails['incoming_email_email'] = "incoming"
# Email account password
gitlab_rails['incoming_email_password'] = "[REDACTED]"
# IMAP server host
gitlab_rails['incoming_email_host'] = "gitlab.example.com"
# IMAP server port
gitlab_rails['incoming_email_port'] = 143
# Whether the IMAP server uses SSL
gitlab_rails['incoming_email_ssl'] = false
# Whether the IMAP server uses StartTLS
gitlab_rails['incoming_email_start_tls'] = false
# The mailbox where incoming mail will end up. Usually "inbox".
gitlab_rails['incoming_email_mailbox_name'] = "inbox"
```
```ruby
# Configuration for Gmail / Google Apps, assumes mailbox gitlab-incoming@gmail.com
gitlab_rails['incoming_email_enabled'] = true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
gitlab_rails['incoming_email_address'] = "gitlab-incoming+%{key}@gmail.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
gitlab_rails['incoming_email_email'] = "gitlab-incoming@gmail.com"
# Email account password
gitlab_rails['incoming_email_password'] = "[REDACTED]"
# IMAP server host
gitlab_rails['incoming_email_host'] = "imap.gmail.com"
# IMAP server port
gitlab_rails['incoming_email_port'] = 993
# Whether the IMAP server uses SSL
gitlab_rails['incoming_email_ssl'] = true
# Whether the IMAP server uses StartTLS
gitlab_rails['incoming_email_start_tls'] = false
# The mailbox where incoming mail will end up. Usually "inbox".
gitlab_rails['incoming_email_mailbox_name'] = "inbox"
```
1. Reconfigure GitLab and restart mailroom for the changes to take effect:
```sh
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart mailroom
```
1. Verify that everything is configured correctly:
```sh
sudo gitlab-rake gitlab:incoming_email:check
```
1. Reply by email should now be working.
### Installations from source
1. Go to the GitLab installation directory:
```sh
cd /home/git/gitlab
```
1. Find the `incoming_email` section in `config/gitlab.yml`, enable the feature
and fill in the details for your specific IMAP server and email account:
```sh
sudo editor config/gitlab.yml
```
```yaml
# Configuration for Postfix mail server, assumes mailbox incoming@gitlab.example.com
incoming_email:
enabled: true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
address: "incoming+%{key}@gitlab.example.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
user: "incoming"
# Email account password
password: "[REDACTED]"
# IMAP server host
host: "gitlab.example.com"
# IMAP server port
port: 143
# Whether the IMAP server uses SSL
ssl: false
# Whether the IMAP server uses StartTLS
start_tls: false
# The mailbox where incoming mail will end up. Usually "inbox".
mailbox: "inbox"
```
```yaml
# Configuration for Gmail / Google Apps, assumes mailbox gitlab-incoming@gmail.com
incoming_email:
enabled: true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
address: "gitlab-incoming+%{key}@gmail.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
user: "gitlab-incoming@gmail.com"
# Email account password
password: "[REDACTED]"
# IMAP server host
host: "imap.gmail.com"
# IMAP server port
port: 993
# Whether the IMAP server uses SSL
ssl: true
# Whether the IMAP server uses StartTLS
start_tls: false
# The mailbox where incoming mail will end up. Usually "inbox".
mailbox: "inbox"
```
1. Enable `mail_room` in the init script at `/etc/default/gitlab`:
```sh
sudo mkdir -p /etc/default
echo 'mail_room_enabled=true' | sudo tee -a /etc/default/gitlab
```
1. Restart GitLab:
```sh
sudo service gitlab restart
```
1. Verify that everything is configured correctly:
```sh
sudo -u git -H bundle exec rake gitlab:incoming_email:check RAILS_ENV=production
```
1. Reply by email should now be working.
### Development
1. Go to the GitLab installation directory.
1. Find the `incoming_email` section in `config/gitlab.yml`, enable the feature and fill in the details for your specific IMAP server and email account:
```yaml
# Configuration for Gmail / Google Apps, assumes mailbox gitlab-incoming@gmail.com
incoming_email:
enabled: true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
address: "gitlab-incoming+%{key}@gmail.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
user: "gitlab-incoming@gmail.com"
# Email account password
password: "[REDACTED]"
# IMAP server host
host: "imap.gmail.com"
# IMAP server port
port: 993
# Whether the IMAP server uses SSL
ssl: true
# Whether the IMAP server uses StartTLS
start_tls: false
# The mailbox where incoming mail will end up. Usually "inbox".
mailbox: "inbox"
```
As mentioned, the part after `+` is ignored, and this will end up in the mailbox for `gitlab-incoming@gmail.com`.
1. Uncomment the `mail_room` line in your `Procfile`:
```yaml
mail_room: bundle exec mail_room -q -c config/mail_room.yml
```
1. Restart GitLab:
```sh
bundle exec foreman start
```
1. Verify that everything is configured correctly:
```sh
bundle exec rake gitlab:incoming_email:check RAILS_ENV=development
```
1. Reply by email should now be working.
# Set up Postfix for Reply by email
This document will take you through the steps of setting up a basic Postfix mail
server with IMAP authentication on Ubuntu, to be used with [Reply by email].
The instructions make the assumption that you will be using the email address `incoming@gitlab.example.com`, that is, username `incoming` on host `gitlab.example.com`. Don't forget to change it to your actual host when executing the example code snippets.
## Configure your server firewall
1. Open up port 25 on your server so that people can send email into the server over SMTP.
2. If the mail server is different from the server running GitLab, open up port 143 on your server so that GitLab can read email from the server over IMAP.
## Install packages
1. Install the `postfix` package if it is not installed already:
```sh
sudo apt-get install postfix
```
When asked about the environment, select 'Internet Site'. When asked to confirm the hostname, make sure it matches `gitlab.example.com`.
1. Install the `mailutils` package.
```sh
sudo apt-get install mailutils
```
## Create user
1. Create a user for incoming email.
```sh
sudo useradd -m -s /bin/bash incoming
```
1. Set a password for this user.
```sh
sudo passwd incoming
```
Be sure not to forget this, you'll need it later.
## Test the out-of-the-box setup
1. Connect to the local SMTP server:
```sh
telnet localhost 25
```
You should see a prompt like this:
```sh
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 gitlab.example.com ESMTP Postfix (Ubuntu)
```
If you get a `Connection refused` error instead, verify that `postfix` is running:
```sh
sudo postfix status
```
If it is not, start it:
```sh
sudo postfix start
```
1. Send the new `incoming` user a dummy email to test SMTP, by entering the following into the SMTP prompt:
```
ehlo localhost
mail from: root@localhost
rcpt to: incoming@localhost
data
Subject: Re: Some issue
Sounds good!
.
quit
```
_**Note:** The `.` is a literal period on its own line._
_**Note:** If you receive an error after entering `rcpt to: incoming@localhost`
then your Postfix `my_network` configuration is not correct. The error will
say 'Temporary lookup failure'. See
[Configure Postfix to receive email from the Internet](#configure-postfix-to-receive-email-from-the-internet)._
1. Check if the `incoming` user received the email:
```sh
su - incoming
mail
```
You should see output like this:
```
"/var/mail/incoming": 1 message 1 unread
>U 1 root@localhost 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
## Configure Postfix to use Maildir-style mailboxes
Courier, which we will install later to add IMAP authentication, requires mailboxes to have the Maildir format, rather than mbox.
1. Configure Postfix to use Maildir-style mailboxes:
```sh
sudo postconf -e "home_mailbox = Maildir/"
```
1. Restart Postfix:
```sh
sudo /etc/init.d/postfix restart
```
1. Test the new setup:
1. Follow steps 1 and 2 of _[Test the out-of-the-box setup](#test-the-out-of-the-box-setup)_.
1. Check if the `incoming` user received the email:
```sh
su - incoming
MAIL=/home/incoming/Maildir
mail
```
You should see output like this:
```
"/home/incoming/Maildir": 1 message 1 unread
>U 1 root@localhost 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
_**Note:** If `mail` returns an error `Maildir: Is a directory` then your
version of `mail` doesn't support Maildir style mailboxes. Install
`heirloom-mailx` by running `sudo apt-get install heirloom-mailx`. Then,
try the above steps again, substituting `heirloom-mailx` for the `mail`
command._
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
## Install the Courier IMAP server
1. Install the `courier-imap` package:
```sh
sudo apt-get install courier-imap
```
## Configure Postfix to receive email from the internet
1. Let Postfix know about the domains that it should consider local:
```sh
sudo postconf -e "mydestination = gitlab.example.com, localhost.localdomain, localhost"
```
1. Let Postfix know about the IPs that it should consider part of the LAN:
We'll assume `192.168.1.0/24` is your local LAN. You can safely skip this step if you don't have other machines in the same local network.
```sh
sudo postconf -e "mynetworks = 127.0.0.0/8, 192.168.1.0/24"
```
1. Configure Postfix to receive mail on all interfaces, which includes the internet:
```sh
sudo postconf -e "inet_interfaces = all"
```
1. Configure Postfix to use the `+` delimiter for sub-addressing:
```sh
sudo postconf -e "recipient_delimiter = +"
```
1. Restart Postfix:
```sh
sudo service postfix restart
```
## Test the final setup
1. Test SMTP under the new setup:
1. Connect to the SMTP server:
```sh
telnet gitlab.example.com 25
```
You should see a prompt like this:
```sh
Trying 123.123.123.123...
Connected to gitlab.example.com.
Escape character is '^]'.
220 gitlab.example.com ESMTP Postfix (Ubuntu)
```
If you get a `Connection refused` error instead, make sure your firewall is setup to allow inbound traffic on port 25.
1. Send the `incoming` user a dummy email to test SMTP, by entering the following into the SMTP prompt:
```
ehlo gitlab.example.com
mail from: root@gitlab.example.com
rcpt to: incoming@gitlab.example.com
data
Subject: Re: Some issue
Sounds good!
.
quit
```
(Note: The `.` is a literal period on its own line)
1. Check if the `incoming` user received the email:
```sh
su - incoming
MAIL=/home/incoming/Maildir
mail
```
You should see output like this:
```
"/home/incoming/Maildir": 1 message 1 unread
>U 1 root@gitlab.example.com 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
1. Test IMAP under the new setup:
1. Connect to the IMAP server:
```sh
telnet gitlab.example.com 143
```
You should see a prompt like this:
```sh
Trying 123.123.123.123...
Connected to mail.example.gitlab.com.
Escape character is '^]'.
- OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION] Courier-IMAP ready. Copyright 1998-2011 Double Precision, Inc. See COPYING for distribution information.
```
1. Sign in as the `incoming` user to test IMAP, by entering the following into the IMAP prompt:
```
a login incoming PASSWORD
```
Replace PASSWORD with the password you set on the `incoming` user earlier.
You should see output like this:
```
a OK LOGIN Ok.
```
1. Disconnect from the IMAP server:
```sh
a logout
```
## Done!
If all the tests were successful, Postfix is all set up and ready to receive email! Continue with the [Reply by email](./README.md) guide to configure GitLab.

# With self-hosted email servers, this is usually the user part of the email address.
user: "gitlab-incoming@gmail.com"
# Email account password
password: "[REDACTED]"
# IMAP server host
host: "imap.gmail.com"
# IMAP server port
port: 993
# Whether the IMAP server uses SSL
ssl: true
# Whether the IMAP server uses StartTLS
start_tls: false
# The mailbox where incoming mail will end up. Usually "inbox".
mailbox: "inbox"
```
1. Enable `mail_room` in the init script at `/etc/default/gitlab`:
```sh
sudo mkdir -p /etc/default
echo 'mail_room_enabled=true' | sudo tee -a /etc/default/gitlab
```
1. Restart GitLab:
```sh
sudo service gitlab restart
```
1. Verify that everything is configured correctly:
```sh
sudo -u git -H bundle exec rake gitlab:incoming_email:check RAILS_ENV=production
```
1. Reply by email should now be working.
### Development
1. Go to the GitLab installation directory.
1. Find the `incoming_email` section in `config/gitlab.yml`, enable the feature and fill in the details for your specific IMAP server and email account:
```yaml
# Configuration for Gmail / Google Apps, assumes mailbox gitlab-incoming@gmail.com
incoming_email:
enabled: true
# The email address including the `%{key}` placeholder that will be replaced to reference the item being replied to.
# The placeholder can be omitted but if present, it must appear in the "user" part of the address (before the `@`).
address: "gitlab-incoming+%{key}@gmail.com"
# Email account username
# With third party providers, this is usually the full email address.
# With self-hosted email servers, this is usually the user part of the email address.
user: "gitlab-incoming@gmail.com"
# Email account password
password: "[REDACTED]"
# IMAP server host
host: "imap.gmail.com"
# IMAP server port
port: 993
# Whether the IMAP server uses SSL
ssl: true
# Whether the IMAP server uses StartTLS
start_tls: false
# The mailbox where incoming mail will end up. Usually "inbox".
mailbox: "inbox"
```
As mentioned, the part after `+` is ignored, and this will end up in the mailbox for `gitlab-incoming@gmail.com`.
1. Uncomment the `mail_room` line in your `Procfile`:
```yaml
mail_room: bundle exec mail_room -q -c config/mail_room.yml
```
1. Restart GitLab:
```sh
bundle exec foreman start
```
1. Verify that everything is configured correctly:
```sh
bundle exec rake gitlab:incoming_email:check RAILS_ENV=development
```
1. Reply by email should now be working.

# Set up Postfix for Reply by email
This document will take you through the steps of setting up a basic Postfix mail server with IMAP authentication on Ubuntu, to be used with Reply by email.
The instructions make the assumption that you will be using the email address `incoming@gitlab.example.com`, that is, username `incoming` on host `gitlab.example.com`. Don't forget to change it to your actual host when executing the example code snippets.
## Configure your server firewall
1. Open up port 25 on your server so that people can send email into the server over SMTP.
2. If the mail server is different from the server running GitLab, open up port 143 on your server so that GitLab can read email from the server over IMAP.
## Install packages
1. Install the `postfix` package if it is not installed already:
```sh
sudo apt-get install postfix
```
When asked about the environment, select 'Internet Site'. When asked to confirm the hostname, make sure it matches `gitlab.example.com`.
1. Install the `mailutils` package.
```sh
sudo apt-get install mailutils
```
## Create user
1. Create a user for incoming email.
```sh
sudo useradd -m -s /bin/bash incoming
```
1. Set a password for this user.
```sh
sudo passwd incoming
```
Be sure not to forget this, you'll need it later.
## Test the out-of-the-box setup
1. Connect to the local SMTP server:
```sh
telnet localhost 25
```
You should see a prompt like this:
```sh
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 gitlab.example.com ESMTP Postfix (Ubuntu)
```
If you get a `Connection refused` error instead, verify that `postfix` is running:
```sh
sudo postfix status
```
If it is not, start it:
```sh
sudo postfix start
```
1. Send the new `incoming` user a dummy email to test SMTP, by entering the following into the SMTP prompt:
```
ehlo localhost
mail from: root@localhost
rcpt to: incoming@localhost
data
Subject: Re: Some issue
Sounds good!
.
quit
```
_**Note:** The `.` is a literal period on its own line._
_**Note:** If you receive an error after entering `rcpt to: incoming@localhost`
then your Postfix `my_network` configuration is not correct. The error will
say 'Temporary lookup failure'. See
[Configure Postfix to receive email from the Internet](#configure-postfix-to-receive-email-from-the-internet)._
1. Check if the `incoming` user received the email:
```sh
su - incoming
mail
```
You should see output like this:
```
"/var/mail/incoming": 1 message 1 unread
>U 1 root@localhost 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
## Configure Postfix to use Maildir-style mailboxes
Courier, which we will install later to add IMAP authentication, requires mailboxes to have the Maildir format, rather than mbox.
1. Configure Postfix to use Maildir-style mailboxes:
```sh
sudo postconf -e "home_mailbox = Maildir/"
```
1. Restart Postfix:
```sh
sudo /etc/init.d/postfix restart
```
1. Test the new setup:
1. Follow steps 1 and 2 of _[Test the out-of-the-box setup](#test-the-out-of-the-box-setup)_.
1. Check if the `incoming` user received the email:
```sh
su - incoming
MAIL=/home/incoming/Maildir
mail
```
You should see output like this:
```
"/home/incoming/Maildir": 1 message 1 unread
>U 1 root@localhost 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
_**Note:** If `mail` returns an error `Maildir: Is a directory` then your
version of `mail` doesn't support Maildir style mailboxes. Install
`heirloom-mailx` by running `sudo apt-get install heirloom-mailx`. Then,
try the above steps again, substituting `heirloom-mailx` for the `mail`
command._
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
## Install the Courier IMAP server
1. Install the `courier-imap` package:
```sh
sudo apt-get install courier-imap
```
## Configure Postfix to receive email from the internet
1. Let Postfix know about the domains that it should consider local:
```sh
sudo postconf -e "mydestination = gitlab.example.com, localhost.localdomain, localhost"
```
1. Let Postfix know about the IPs that it should consider part of the LAN:
We'll assume `192.168.1.0/24` is your local LAN. You can safely skip this step if you don't have other machines in the same local network.
```sh
sudo postconf -e "mynetworks = 127.0.0.0/8, 192.168.1.0/24"
```
1. Configure Postfix to receive mail on all interfaces, which includes the internet:
```sh
sudo postconf -e "inet_interfaces = all"
```
1. Configure Postfix to use the `+` delimiter for sub-addressing:
```sh
sudo postconf -e "recipient_delimiter = +"
```
1. Restart Postfix:
```sh
sudo service postfix restart
```
## Test the final setup
1. Test SMTP under the new setup:
1. Connect to the SMTP server:
```sh
telnet gitlab.example.com 25
```
You should see a prompt like this:
```sh
Trying 123.123.123.123...
Connected to gitlab.example.com.
Escape character is '^]'.
220 gitlab.example.com ESMTP Postfix (Ubuntu)
```
If you get a `Connection refused` error instead, make sure your firewall is setup to allow inbound traffic on port 25.
1. Send the `incoming` user a dummy email to test SMTP, by entering the following into the SMTP prompt:
```
ehlo gitlab.example.com
mail from: root@gitlab.example.com
rcpt to: incoming@gitlab.example.com
data
Subject: Re: Some issue
Sounds good!
.
quit
```
(Note: The `.` is a literal period on its own line)
1. Check if the `incoming` user received the email:
```sh
su - incoming
MAIL=/home/incoming/Maildir
mail
```
You should see output like this:
```
"/home/incoming/Maildir": 1 message 1 unread
>U 1 root@gitlab.example.com 59/2842 Re: Some issue
```
Quit the mail app:
```sh
q
```
1. Log out of the `incoming` account and go back to being `root`:
```sh
logout
```
1. Test IMAP under the new setup:
1. Connect to the IMAP server:
```sh
telnet gitlab.example.com 143
```
You should see a prompt like this:
```sh
Trying 123.123.123.123...
Connected to mail.example.gitlab.com.
Escape character is '^]'.
- OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION] Courier-IMAP ready. Copyright 1998-2011 Double Precision, Inc. See COPYING for distribution information.
```
1. Sign in as the `incoming` user to test IMAP, by entering the following into the IMAP prompt:
```
a login incoming PASSWORD
```
Replace PASSWORD with the password you set on the `incoming` user earlier.
You should see output like this:
```
a OK LOGIN Ok.
```
1. Disconnect from the IMAP server:
```sh
a logout
```
## Done!
If all the tests were successful, Postfix is all set up and ready to receive email! Continue with the [Reply by email](./README.md) guide to configure GitLab.
