Guys,
I've been beating my head against a problem for a couple of days now ... maybe
someone can point me in the right direction ...?
I'm running SA 3.4.1 on Fedora 22. I think this problem started happening when
I upgraded from 3.4.0 on Fedora 21. In both cases, SA is running from within
MimeDefang 2.78.
Basically ... Mail is being deferred if any of the To or Cc addresses in the
mail *header* fail DNS resolution. So, if I receive a mail:
To: me@mydomain.comCc: some...@bogusdomain.com
Mail sits in teh queue on my server until the NS for bogusdomain.com comes back
to life. If I add an entry for the bogus domain to my DNS server, all is fine.
I can see the query come into my nameserver logs if I do this.
My guess is that some of the processing that SA is doing generates the lookup
on To/Cc addresses, since if I take MD out of my sendmail.mc, this doesn't
happen.
I'm presently working my way through rulesets, turning things off.
Does anyone have a better suggestion?
Thanks
Judy.
