Thanks Peter. Not sure why the header images were removed from the e-mail.
In any case, they basically showed the e-mail bouncing around within my
mail server, presumingly as its passes through various greylist,
blacklist, and anti-spam filtering. Typically headers looks like:
Hop 1: User tool -> User mail system mapi
Hop 2: User mapi -> User mail system SMTP server (TLS)
Hop 3: User mail SMTP -> mail.seaplace.org (Postfix - obviously
external IP address)
Hop 4: mail.seaplace.org (localhost) -> Amavsid-new (localhost)
Hop 5: localhost -> mail.seaplace.org (Postfix)
Hop 6: spoe.seaplace.org (external address???) -> mail.seaplace.org
(Postfix) /* This is where the delay occurs */
Hop 7: mail.seaplace.org (localhost) -> Amavsid-new (localhost)
Hop 8: localhost -> mail.seaplace.org (Postfix)
Hop 9: spoe.seaplace.org (external address) -> Recipient server
spoe/mail.seaplace.org is my externally connected mail server.
The ~1700 users are splattered all over the world, although
predominately in the USA.

We had a similar problem when our list host decided to throttle our mail. Our
gmail members get postings within seconds, others can get them hours later. The
more list traffic, then longer the delays, and sometimes they arrive out of
order.
But that was a shared mail server. Is this mail server your own? And our
members are with random mail providers. Are the list members all on the same
domain?

Hi all.
Been casually fighting a problem for a couple of months now and have
finally decided to ask for help.
I have a somewhat large mailing list, about 1700 users, that is
generally working just fine. However, some users are seeing LONG delays
(like 4+ hours) on mail delivery while other users, in the same
organization, get sub-minute delivery. Specifically, the step 6 delay
in the header analysis below is typically 2 seconds.
In the header analysis below please note that mail.seaplace.org and
spoe.seaplace.org are just two names (DNS A records) pointing to the
same box. The postfix main.cf mydestination parameter includes both.
I highly suspect this is something within Postfix and hope the list's
extensive experience might help.
Thanks in advance,
Kevin
