In-house we've set up a server to act as a secondary MX record to the
domains we host mail. The server then forwards these messages to the
actual mail server the domain is hosted. The goal is that, in the event
a server dies, mail is still collected and gathered, waiting to be
delivered to the proper server. The setup of qmail follows the toaster
guide.
Because the actual mail servers are working fine - the server is
getting nothing but spam and junk emails, filling the queue is growing
to huge sizes over 117K in messages! Spamassassin is barely able to
keep up with the load, and I'm sure clamav isn't far behind. We've been
pruning the queue of messages using qmHandle, but we need something that
handles things on its own. We've also set the queue lifetime to be 12
hours.
Some ideas we've been comtemplation to fix the issue:
- another failover server set up the same way that handles 1/2 the
domains secondary MX records.
- some qmail patch that reject the mail if the actual server is still
online and operational
- keep failover server offline until needed
Any suggestions on this are appreciated. Thanks.
