Hello,
Personally, I think it is more simple and convenient to migrate system users' mail to the virtual-user setup (i.e. two separate logins, e.g. 'user' for SSH and 'user@domain.com' for mail ).
Here are the relevant portions of my postfix config:
mydestination = localhost local_recipient_maps = $virtual_mailbox_maps $virtual_alias_maps mydomain = domain.com # your 'local' host/domain name myhostname = domain.com # your 'local' host/domain name smtpd_recipient_restrictions = ....., reject_unverified_recipient, ..... # to do LMTP-based verification of incoming mail unknown_local_recipient_reject_code = 550 unverified_recipient_reject_code = 550 virtual_alias_maps = hash:/usr/ext/mail/valias virtual_mailbox_domains = hash:/usr/ext/mail/vdomains virtual_transport = lmtp:unix:private/dovecot-lmtp
/usr/ext/mail/valias defines additional redirections like postmaster@domain.com admin@domain.com root@domain.com admin@domain.com
/usr/ext/mail/vdomains is an access-map file with records for supported domains, like: domain.com OK
Also adjust 'root' record in /etc/mail/aliases to point to qualified admin's mail address (admin@domain.com)
Best wishes Eugene

Hi,
I have a mailsystem where i have some local users with shell access and full home dirs which receive mail and also several SQL virtual users only for mail. With the virtual users, everything works fine. Mail is delivered via LMTP and also sieve works :) The SQL Lookup knows what to do with username@domain.com
The problem is the system user. If exim delivers the mail to the lmtp socket, the LMTPd can't find username@local.host I would be able to specify the global auth_username_format=%n but then my SQL queries break and I like the possibility to have xx@domain1.com and xx@domain2.com routed to two different accounts.
As I have seen in the source, I can't specify username_format=%n in the passdb { driver = pam } backend. Do you have any suggestion how to solve this issue?
thanks Philipp
