Hi list,
I'm trying to integrate dspam filtering into my postfix system. The
way I have it now works for local users but when a user has an alias
to an external domain the mail bounces. This server is for receiving
mail only, so no submission is needed.

This is the mail system at host chuck.redknot.nl.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system
<martijndemun...@chuck.redknot.nl> (expanded from <martijndemunnik>):
unknown
user: "martijndemunnik"
Reporting-MTA: dns; chuck.redknot.nl
X-Postfix-Queue-ID: 1C455D2A2
X-Postfix-Sender: rfc822; mart...@youngguns.nl
Arrival-Date: Thu, 2 Sep 2010 21:58:12 +0200 (CEST)
Final-Recipient: rfc822; martijndemun...@chuck.redknot.nl
Original-Recipient: rfc822;martijndemunnik
Action: failed
Status: 5.1.1
Diagnostic-Code: X-Postfix; unknown user: "martijndemunnik"
---
The virtual file contains:
just...@suezkade.nl martijndemun...@gmail.com
I'm sure this is because I pass "--user ${mailbox}" to the dspam
command, but I'm not sure how to solve this. I want dspam to learn
what is spam for my local user, so I guess dspam should be as close as
possible to final delivery. There is also another problem. Dspam calls
clamav to scan the message for viruses. When A virus is found dspam
dies because the shell can't handle a negative error return code. The
dspam list told me to use the server part of dspam to fix this and let
postfix talk to dspam with lmtp. I'm not sure how to do this.
virtual_transport doesn't seem to have any effect because I'm not
using virtual_domains?
Any ideas?
Thanks,
Martijn
