Amavis DNS query timeout

[Tim Smith]

Well surely amavis is using the same DNS servers as the server ?
Therefore a "dig" on the server indicates that my DNS lookups are
working, and therefore why I am saying amavis is not right when it
says "DNS timeout".

If you could point me in the right direction of how to collect the
further troubleshooting data you need, I'll be happy to oblige !
