I'm trying to investigate a 2 hour lag on mail delivery for a mailing
list, and am seeing something that seems a wee bit odd ... based on the
Received headers, from what I can tell, the 2 hour lag is within postfix
itself:

Received: from postgresql.org (svr1.postgresql.org [200.46.204.71])
     by svr1.postgresql.org (Postfix) with ESMTP id E14B1DBC8F;
     Sat, 19 Nov 2005 16:39:30 -0400 (AST)
X-Original-To: pgsql-general-postgresql.orglocalhost.postgresql.org
Received: from localhost (av.hub.org [200.46.204.144])
     by svr1.postgresql.org (Postfix) with ESMTP id ADB11DBC7D
     for <pgsql-general-postgresql.orglocalhost.postgresql.org>; Sat,
     19 Nov 2005 14:38:36 -0400 (AST)
Received: from svr1.postgresql.org ([200.46.204.71])

So, its going *through* av.hub.org fairly quickly, but looks like its being
held in the postfix queue before even being passed over to majordomo for up to
2 hours ... which makes no sense, since the queue is fairly empty (511 messages
right now) ...

It doesn't happen on all messages, but seems to be relatively consistent
for those going through pgsql-general, which is even more odd, since they
are all configured exactly the same ...

So, is there something that I can look at/do to try and debug *why* there
is that delay there?
