thanks for the info -- yeah, although i realize now that i was being
ambiguous, i meant why does the smtp server take so long to send
messages from the one account (and sometimes doesn't seem to send them
at all -- no longer in the queue but never arrive at destination) while
the other goes immediately. the delay is definitely at the smtp server,
but i haven't quite figured out why it takes 6+ minutes to process a
message that is queued while i sent other messages that were immediately
processed as soon as they hit the queue. oh well, looks like i should
setup a freebsd box for smtp instead of using the windows box from
work...
thanks again,
jon

It all depends on the server and the route that the message is
taking. Then your come-back copy depends on the return path.

Let's look at the headers of the first message, specifically at
the date/time stamps:
| Received: from hub.freebsd.org (hub.FreeBSD.org [216.136.204.18]) by
| mx2.freebsd.org (Postfix) with ESMTP id 7F7205572F;

Okay, the message was submitted at 03:16:27 -0500, and here it's
already been received by the FreeBSD machines, passed through the
mailing list server, and on it's way back out within six-and-a-half
minutes. That is, assuming that all servers are in perfect time
sync. If they're not, the overall end-to-end time could easily be
just a matter of a few seconds.

This would seem to be the place where most of the delay
occurred.
However, it would be difficult to determine what caused the delay.
It could be a problem with the sending system, or it could be a
problem with the receiving system. But without more information
(including the logs of both the sending & receiving systems), it's
hard to tell what was the real cause.

And that's the original submission.
Now, let's look at the headers of the second message:
| Received: from hub.freebsd.org (hub.FreeBSD.org [216.136.204.18]) by
| mx2.freebsd.org (Postfix) with ESMTP id 4F83A55B10; Sun, 11 Aug
| 2002 01:32:54 -0700 (PDT) (envelope-from
| owner-freebsd-chat@FreeBSD.ORG)
Well, this message was received, processed, and re-transmitted
in
just five seconds, if you believe the time stamps.

Here's the original message submission.
Looking at the other headers (which I omitted), it would appear
that the paths are pretty much identical between the two messages.
