Thanks Scott for very helpful info you provide.
I like to ask another thing is there a physical limit to the number of SMTP
processes you can create. How can I come up with the optimum setting?
What kinds of measures I have to take into account.
Thnx alot
Tolga

SMTP process that will try to send E-mail in the queue. It will try to send
one, then try to send the next, and so forth. Even if you have 30+
available SMTP processes, only one will be used for the spool. So the goal
is to not allow a bunch of E-mail into the queue, and have them delivered
successfully on the first attempt.
