Are both configured the same? For example, are they set up to use the
Mail Router first (or only the mail router?)

If they're timing out using MX entries from the recipients domains
first, before the mail router, that could easily give the extra time
(ie 30 seconds for each MX record, timing out because or erroring

I see this from time to time with my MAILTOOL Plus software which also
bypasses IBM's SMTP server.

I'm trying to figure out why sending an email on one IBM i server is
performed so much faster than the same task on a different server, even
though the first server is a much slower box. We have a model 520 that
sends emails pretty quick (using Scott Klement's SMTPSendMail replacement
for the QtmmSendMail API), while our E4B is a REAL SNAIL (using the same
programs). It can takes minutes for each email sent on the E4B, while a
matter of moments on the 520.

I'm fairly ignorant on SMTP config and have done my best to compare apples
to apples between systems, but can't see any differences.

Any suggestions?
