[Dovecot] Sendmail + Deliver as an LDA
Need help with setup/config.
Current situation: (dovecot version : 1.1.7)
we have system users and virtual users. (with different domains)
Virtual users have procmail as LDA
Now we want "deliver" to become the LDA
I'm confused reading http://wiki.dovecot.org/LDA/Sendmail
sendmail.mc:

What setup do we need for both system and virtual users ?
Help would be appreciated !
thx Natan

I'm confused reading http://wiki.dovecot.org/LDA/Sendmail [...]
To use dovecot's deliver as sendmail's local mailer you need the following lines in your sendmail.mc:
FEATURE(local_procmail', /local/dovecot/libexec/dovecot/deliver',deliver -d $u') MODIFY_MAILER_FLAGS(LOCAL', `-f')
Change path to dovecot's deliver to fit your installation.
The second line is needed only if your deliver does not support "-f envelope_sender" command line argument or if dovecot and sendmail do not "play well together" with "empty" (<>) envelope sender. I do not think it is required but http://wiki.dovecot.org/LDA/Sendmail mentions it for some (unexplained) reasons.
the above changes should not affect deliveries to virtual users [ unless you use *VERY* unusual sendmail configuration ]
P.S. Do you reject messages to non existing virtual users in reply to "RCPT TO:"?

"deliver" is working fine.
/usr/libexec/dovecot/deliver -d test@domain1 < testmail
creates the virtual mailbox. (uid,gid,mail,home through passwd sql)
Currently we have a virtualusertable
(FEATURE(virtusertable',hash -o /etc/mail/virtusertable')dnl)
virtualusertable looks like:
user1@domain1 user1@hotmail.com
user2@domain1 user2@hotmail.com
@domain1 system-user
For the moment, an email sent to test@domain1 is forwarded to the system-user.
The system-user has a .procmail-config where he places the incomming mail into the correct virtual-mailbox.
Now we have replaced "local_procmail" with "deliver":
FEATURE(local_procmail', /usr/libexec/dovecot/deliver',`deliver -d $u')
an email sent to test@domain1 is placed in the system-user's real-mailbox.
How to keep the external-forward-functionality of the virtualusertable and to be able to deliver into the virtual-mailbox?
Regards,
Natan

You just need to set system-user in you alias file to execute a program (procmail), this way it overrides the local delivery agent

Currently we have a virtualusertable (FEATURE(
virtusertable',hash -o /etc/mail/virtusertable')dnl)
SOT: do not use -o flag above. It makes sendmail start "happily" even when virtusertable is inaccessible.
virtualusertable looks like:
user1@domain1 user1@hotmail.com user2@domain1 user2@hotmail.com @domain1 system-user
For the moment, an email sent to test@domain1 is forwarded to the system-user. The system-user has a .procmail-config where he places the incomming mail into the correct virtual-mailbox.

How to keep the external-forward-functionality of the virtualusertable and to be able to deliver into the virtual-mailbox?
Which of sendmail.cf based solutions below do you prefer? a) "cleaner" but requiring small patch of *.m4 files used to generate sendmail.cf [ would require repeating patching after every sendmail upgrade ] b) "messy" with many related entries in different maps but without patching
P.S. Some question that may help to choose the best recipe:
- How many virtual mailboxes do you support?
- Do you keep dovecot's userdb in plain text file?

Some question that may help to choose the best recipe:
- How many virtual mailboxes do you support? for the moment only 40
(that's because our users don't like procmail -> too complicated - hence the reason for switching to "deliver")
- Do you keep dovecot's userdb in plain text file?
dovecot is looking-up the system users (plain text)
userdb passwd {}
and a lookup in mysql database
userdb sql {args = /etc/dovecot-sql.conf }
Which of sendmail.cf based solutions below do you prefer?
don't know. For the moment I prefer a "working" solution ;-)
a) "cleaner" but requiring small patch of *.m4 files used to generate sendmail.cf [ would require repeating patching after every sendmail upgrade ] b) "messy" with many related entries in different maps but without patching
Can you describe your prefered ("messy" or "cleaner") way to go ?

Recipe for delivery to virtual dovecot domains via procmail scripts

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

Is there also a recipe for delivery to virtual dovecot domains via "deliver" ?
what I would like to achieve:
user1@example.net -> forwarded to user1@hotmail.com
user2@example.net -> delivered to local mailbox (a virtual dovecot mailbox)
for the first one you need FEATURE(`virtusertable')
for the second one you need FEATURE(`mailertable')
