Once again, no network is an island, and I'm being reminded of that by
bounced mail.
Scenario:
I'm connecting one of my linux boxes to the net via a UU.net ppp account.
Internally, I've got 2 linux boxes: 1 is the PPP host, mail host, DNS host
and soon to be IP Masquerade host, and the other one is my general
workstation all nicely configured for all of my computing needs.
I've got fetchmail configured to retrieve mail from several different
accounts and send the mail directly to my workstation, bypassing the
qmail/ppp host, though qmail on the qmail/ppp host is configured with an
alias which forwards all mail to my workstation. Fine.
The one other issue is that I've set up DNS on the qmail/ppp host as both a
caching as well as the nameserver for my fictitious internal network,
ericberg.com. Now, here's where I think that I run into problems.
Problems:
Most mail works just fine, but some domains require the domain from which
mail originates to resolve -- a reasonable requirement. Anyway, ericberg.com
doesn't.
Here's the log entry for the failure:
May 19 08:57:37 moby qmail: 927118657.368399 delivery 1: deferral:
Connected_to_199.182.120.56_but_sender_was_rejected./Remote_host_said:_451_<[EMAIL PROTECTED]>..._Domain_must_resolve/
How should a qmail Admin go about thinking about this and solving the
problem?
-Eric.
