Phil, thanks for your suggestions.
This is the server of the future, all right :(...I guess decent e-mail
performance is an unworthy component of e-business. Oh, I know...CFINT
controls it to make sure e-mail is delivered promptly.
I assume Lotus Notes uses the same API and I assume their performance is
somewhat better. I guess I'll stop MSF and restart it and see if I can
figure out what's up....

Reeve,
MSF performance is a complaint often voiced. If you're sending only one
e-mail address at a time to the API then you may want look at sending an
array of e-mail addresses. This may speed things up if you're sending the
same e-mail to 100's of recipients.
If you're timing the mail delivery you probably should start counting when
the e-mail hits your firewall. Then you'll be able to tell where the
bottleneck is. Maybe your firewall can log when smtp mail passes through
it?
