Update on previous email: After upgrading to latest snapshot (OpenBSD
7.3-beta (GENERIC.MP) #1109:), MX errors have gone away and outbound
mail is flowing again.
So, clearly, whatever upstream issue in the OS that was preventing name
look-ups has been resolved.
Hallelujah.

No solution here yet. I suspect you're correct in your conjecture about
the source of the issue. Looking at the smptd source tree on CVS, I see
no recent code changes that would explain the regression. I'm going to
try upgrading OpenBSD snapshots later today.

Has no one else experienced this? Scott, did you ever find a
resolution? For me it's only on a relay box mailing status reports
so I put a special rule in smtpd.conf to send it straight to the IP
of the other box on the network, so not a huge deal, but eventually
I will have to upgrade my real mail server from 7.2 to 7.3 and I
can't have my mail stop working so I'm curious to track down the
real cause here. DNS resolution works fine for everything else on
the machine. I notice that OpenSMTPD is 7.0.0 on both boxes so I'm
actually inclined to think the changes may have been on the OpenBSD
side of things and I might take this to misc@ or tech@ if we don't
get anywhere here.
Thanks for your time everyone. I sincerely appreciate all the work
everyone has put into these products, and they create a great deal
of value for me in my life. Best wishes to all.

Just upgraded snapshots from OpenBSD 7.2-current (GENERIC.MP
<http://GENERIC.MP>) #1047 to OpenBSD 7.3-beta (GENERIC.MP
<http://GENERIC.MP>) #1100. So, smtpd version is OpenSMTPD 7.0.0.
All of a sudden I'm getting MX resolution errors that were not
occurring immediately prior to the upgrade, e.g.
Mar 10 11:56:20 callistino smtpd[81842]: smtp-out: Failed to
resolve MX for [relay:gmail.com <http://gmail.com>,smtp]:
Temporary failure in MX lookup
Mar 10 11:56:20 callistino smtpd[81842]: 0000000000000000 mta

<mailto:i...@datagenius.com> to=<datagen...@gmail.com>
<mailto:datagen...@gmail.com> rcpt=<-> source="-" relay="gmail.com
<http://gmail.com>" delay=6m40s result="TempFail" stat="Temporary
failure in MX lookup"
There have been no smtpd configuration changes, smtpd.conf is
same as just prior to the snapshot upgrade.
Host name resolution using the dig and host all seem to work fine,
so it doesn't seem to be a connectivity issue.
Can anyone kindly give me some pointers on how to troubleshoot
this issue?
Many thanks in advance.
