Having 19 SMTP32.EXE processes in memory isn't abnormal (it just means that
IMail is trying to deliver 19 different E-mails at the same time, which
often occurs when mailing list E-mail goes out).
>It is a virus?
Why do you think it is a virus?
Note that if one person has a virus and it is spreading, it will normally
only use one or several SMTP processes (and won't use any more CPU time
than normal E-mail with the same volume). More likely, it could be someone
sending spam.

Note that a standard virus scanner won't be able to detect viruses in
E-mail, so that step won't be too useful (unless you think the server
itself is infected, but that isn't likely).

This may seem like a dumb question, but have you checked the IMail logs to
see what all that outgoing mail is?
I'm assuming that when you say the CPU usage is at 100% and that there are
19 SMTP processes, but the situation is critical, that this has been
happening for a long time (and that you didn't just once see the CPU at
100% with a lot of SMTP processes). In that case, someone is sending a LOT
of outgoing E-mail, probably spam (or a mail loop). Your IMail log file
will clue you in as to who is doing it and why.
