"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?

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')

1. Change path to dovecot's deliver to fit your installation.

2. 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.

3. 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:"?

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

Some question that may help to choose the best recipe:

1. 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")

2. 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 ?

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')

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
