just figured it out.
its that qmail bug.
the 10 year old one where if an mx is down for maint, qmail won't try
other mx records.
(sorta)
if the FIRST TIME qmail sends an email, it hits mx1, it seems to 'stick'
there, and will NEVER try mx2,3, or 4.
we run into this all the time.
is it a bug? depending on who you ask.
if it prevents sending email to RFC compliant mail servers, than I think
its a bug.
if it violates RFC's so badly, that it prevents sending email to RFC
compliant mail servers, than I think its a bug.
<http://www.mail-archive.com/qmail [at] id/msg45399.html>
there are 'UNOFFICIAL' patches out there to help qmail conform to RFC's
in this area, but 10 years and counting, its never made it into the
official build.
causes a lot of anger, back and forth when this patch is discussed.
