Forward all (or selective domains) outgoing email to a Barracuda anti-spam appliance
Posted on 2008-10-24
I have a mailserver with around 1000 domains and 8000 popboxes, it's running Qmail and ClamAV, however occasionally a blacklist detects a virus from our IP and blocks the mailserver temporarily. This, despite the fact we have ClamAV and qmail-scanner installed.
We have a Barracuda Anti-spam appliance for incoming mail, but now want to route outgoing email through the Barracuda as well. My question is, how do i configure Qmail for this?
/var/qmail/control/smtproutes is used to forward incoming email to another address, but how can i tell qmail to forward outgoing email to the Barracuda?
