It’s 99.9% sure that you have a CNAME there somewhere.
tg@blau:~ $ host garkin.steigies.net
garkin.steigies.net CNAME chumley.debian.net
chumley.debian.net CNAME steigies.no-ip.org
steigies.no-ip.org A 220.127.116.11
Heh, all that user support in #sendmail on freenode pays off.
I knew the problem without even trying, on the first time
reading about it.
Basically it boils down to: CNAME breaks internet eMail, period.
If you want to send eMails from one domain, you MUST NOT use a
CNAME RR for that domain or one of its components.
The dyndns case is a bit difficult… see whether you can get by
with not needing an A RR, or whether an RFC1918 A RR works; this
works with eMail if you add an MX RR, like:
garkin.steigies.net MX 10 spool.mail.gandi.net
garkin.steigies.net MX 50 fb.mail.gandi.net
Add that, remove the CNAME, and add…
garkin.steigies.net A 192.168.x.y
… or something like that, if you must, and that works.
This will, of course, break ssh to that hostname from
the outside, but ~/.ssh/config entry…
… will fix t̲h̲a̲t̲.
