I'm in the final stages of testing my e-mail server to come and I seem to have hit a roadblock.

One option of current vpopmail is to store all aliases in a valias table, that looks like this:

+-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | alias | char(32) | NO | MUL | | | | domain | char(64) | NO | | | | | valias_line | text | NO | | | | +-------------+----------+------+-----+---------+-------+

where valias_line could be either an e-mail address (preceded by an ampersand) or a command (piped to vacation for example).

I have already accepted a message for an aliased address, but the MTA isn't going to be rewriting the envelope address, so how can I get dovecot's deliver to dereference the alias and deliver to the correct Inbox? Because of the number of other hops[1] that the message is going through, I don't want to rewrite the destination address unless I really have to, but if that is the only option, that is what I'll have to do.

Thoughts?

1. inbound e-mail hits a qpsmtpd instance which validates e-mails using several different filtering techniques. Next the mail gets fed to a dspam appliance running two Postfix queues (one before dspam and one after). Mail that isn't quarantine by dspam gets sent to the delivery server (currently running qmail) and delivered to the final destination (modulo sieve rules under deliver). The only place I could conceivably rewrite the address would be the second Postfix queue.
