Normally, when you send an email, the New Message Window closes after you
hit
the Send button. However, sometimes, when I send an email, the Mew
Message
Window remains open, although the message appears to have gone through
(in
fact it gets scanned by the antivirus, and it is copied in the sent items
folder). However, I always remain with a doubt wheter the mail has gone
through or not, and I send it again. Any clue why this may be happening?
F.Y.I. I use an IMAP server.
