Duplicate outgoing emails, Outlook2003, PC-Cillin

[Richard Thomas]

We are having problems with certain PCs sending multiple duplicate
emails. The common factors seem to be Outlook 2003, pc-cillin and large
(~3MB) files.

Checking on the mail server (SMTP), when the problem occurs, it seems
that several (up to 4) connections are made from the client. It is
almost as if Outlook gets so far through uploading, decides that it
hasn't succeeded and then starts another. As you can imagine, people who
receive 37x3MB emails in their inbox are not too happy and it craters
our WAN (especially if the recipients of those emails are on the same
LAN as the person sending. Kills going up, kills coming down) and leads
to us here in MIS receiving phone calls that people aren't able to get
on the systems they need and can't get their work done.

Has anyone run across this before? Am I looking in the right direction
with pc-cillin? And is there any solution other than disabling it (if
that even is a solution)

This is often a symptom of having your antivirus program scan outgoping
mail. There's NEVER a reason to do that. DIsable email scanning and see if
that helps.
