Re: [IMail Forum] IMail bouncing back E-mail for no stated reason

[Matt]

The DNS server is Windows 2003 DNS running on the same box as IMail and 
it resolves everything else just fine.  I started up a Web browser on 
that box and was able to resolve to the problematic domain's Web site 
without a hitch, probably because the fail over worked properly, but 
IMail wasn't failing over to the secondary DNS for some reason for the 
MX lookup.

I also tested my DNS server by doing queries off of it for the same 
records on that domain and that worked just fine, it can find the 
appropriate MX records, but IMail for some reason couldn't.

Note that I have both domain caching and failed domain skipping turned 
off in IMail and am running 8.15H1.

Is it possible that IMail doesn't properly handle a failed primary 
nameserver?  Or maybe there is something else going on 
(non-standard/error) with the records that is messing it up for this 
domain that is only apparent when the primary nameserver is down?

Thanks,
Matt

Imail queries the DNS it's told to use.
THAT DNS, not Imail, is responsible for resolution, which includes 
handling DNS timeouts.
