Recipe for delivery to virtual dovecot domains via procmail scripts

1. sendmail.mc lines [recompile it to sendmail.cf]

FEATURE(mailertable') FEATURE(virtusertable') MAILER(`procmail') LOCAL_CONFIG dnl File to keep non local domains processed via virtusertable F{VirtHost}/etc/mail/virtual-domains

2. mailertable lines [recompile it with makemap program]

deliver messages to example.net domain via procmail script

# /etc/procmailrcs/example.net.rc # procmail treats scripts in /etc/procmailrcs in special way # if executed as root changes uid to uid of the script file owner example.net procmail:/etc/procmailrcs/example.net.rc

3. access (database/file) lines [recompile it with makemap program]

accept messages addressesed to example.net from anywhere

to:example.net RELAY

4. /etc/mail/virtual-domains file

example.net

5. Check that example.net *IS NOT* listed on list on local email domains

echo '$=w' | sendmail -bt

If it is then 5a) disable auto-detection of local email domains http://www.sendmail.org/m4/tweaking_config.html#confDONT_PROBE_INTERFACES 5b) add local domains missing after turning off auto-detection manually [as mentioned in http://www.sendmail.org/faq/section4#4.5 ]

As I wrote it is a little bit messy and requires many different entries for single virtual domain but no patching of *.m4 files is required.

P.S. *IF* you add the line below to sendmail.mc define(`_VIRTUSER_STOP_ONE_LEVEL_RECURSION_') *THEN* you can list existing dovecot virtual users in virtusertable and reject remaining addresses

user1@example.net %0 user2@example.net %0 @example.net error:nouser User Unknown
