Fixed this issue. My transport table was having a "virtual:" entry against my domain name instead of "dovecot:"

Now all is working! :)

Hi

I have been able to setup postfix and dovecot using postgres as the backend store with virtual user maps on Ubuntu 12.04 LTS Server.

I have been following instructions from here: http://wiki2.dovecot.org/HowTo/DovecotPostgresql

I haven't setup postfix to use saslauthd and PAM, instead I am using dovecot for SASL authentication. Rest of the table structures and query files are the same as from the wiki.

SASL authentication works correctly for SMTP POP IMAP.

I am able to send emails from a mail client such as Thunderbird with SASL authentication.

However I am not able to receive emails for virtual users. I cannot figure out why. System users are getting their emails in the mail box correctly. Postfix fires the mailbox_command to hand over the mail to dovecot.

This is how my *mail.log* looks when I send emails from an external domain:

Nov 6 06:48:21 localhost postfix/smtpd[20053]: E075280C52: client= mail-ee0-f41.google.com[74.125.83.41] Nov 6 06:48:22 localhost postfix/cleanup[20064]: E075280C52: message-id=< CAJ+V0eCU891rSzSMVbcSy4zsRUk5GUp58b70Wv_WgZxLbKuyLw@mail.gmail.com> Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: from=< me@gmail.com>, size=3124, nrcpt=1 (queue active) *Nov 6 06:48:22 localhost postfix/virtual[20066]: E075280C52: to=someone@mydomain.com>, relay=virtual, delay=0.85, delays=0.7/0.02/0/0.13, dsn=2.0.0, status=sent (delivered to maildir)* Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: removed Nov 6 06:48:22 localhost postfix/smtpd[20053]: disconnect from mail-ee0-f41.google.com[74.125.83.41]

Postfix seems to deliver the mail to maildir instead of the home directory of the virtual user. Incase of the system user, the logs indicate that the mailbox_command was fired and I do get to see the mail in the inbox.

My postfix *main.cf http://main.cf*:

I have included the virtual_transport parameter to indicate that dovecot is running as LDA. I have also included the pgsql query file in the virtual_mailbox_maps parameter.

My *mailboxes.cf http://mailboxes.cf *file which points the email id of the virtual user to the appropriate mail path:

user=mailreader password=secret dbname=mails table=postfix_mailboxes select_field=mailbox where_field=userid hosts=localhost

I have included the dovecot LDA service line above so that postfix can deliver to virtual users as per: http://wiki2.dovecot.org/LDA/Postfix

This is my *doveconf -n* output:

I have setup *mail_location *to point to the home directory of vmailuser under which for the given domain the virtual users mail dir is created. However, the mails clearly don't seem to get delivered for the virtual user.

Any help to fix this would be appreciated. Thanks! :)
