RE: QTMMSENDMAIL performance -- MIDRANGE-L

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?
