Previous version used CMFMailIn and didn't work anymore.
Remove useless sendMailToZope.py script.

Like old sendMailToERP5.py, it can be used directly to deliver mails from
postfix to ERP5.

Main improvements over previous implementation are:
- fix bug losing mail silently if ERP5 instance returns a HTTP status >= 300
- ingestion map to get options according to the recipient
