Hi,

I have configured the MTA (exim4) to put the messages for my local users at /var/mail. If the user does not exist as true unix user, it looks at a postgresql database and if the user exists there, it delivers the message at /var/mail/virtual

Example: User fred is a unix user, and peter is a virtual user.

If i send a mail to fred@mydomain.org, the message is stored at /var/mail/fred (im using exim's append for transport).

If i send a mail to peter@mydomain.org, the message is stored at /var/mail/virtual/peter

With the defaul configuration from debian, dovecot is capable serving the local users mailbox (and its working at the moment). Im using only IMAP (i see there is an option for pop3, but im not interested in that atm).

I think i know how to change the config file to serve only virtual users using the postgres module.

Can anyone tell me how to serve them both at the same time? As I understand it, what i need is to make dovecot try to validate a user againt the local user database (its using pam for that at the moment), and if it fail, try with postres. But i dont know how (or if its possible at all).

Thanks.
