Are you using the SMTP server belonging to the ISP which provides the
connection? This is where many people get it wrong.

POP3 is completely unrelated, so don't use it for any inferences.

I believe that Microsoft ought to have output the description to the screen
rather than give hexadecimal numbers and refer to the user to a

It sounds as if the problem is not related to the AV. It is only an illusion
because the AV sits on top of the network layer.

A few weeks ago I came across similar symptoms. A professor could only send
one message at a time. It must have been an odd bug.
