Disable email scanning (incoming & outgoing) by your anti-virus application.
It provides no additional protection, it's the most likely cause of your
problem, and even Symantec says it's not necessary:

Disabling Email Scanning does not leave you unprotected against viruses that
are distributed as email attachments. Norton AntiVirus Auto-Protect scans
incoming files as they are saved to your hard drive, including email and
email attachments. Email Scanning is just another layer on top of this. To
make sure that Auto-Protect is providing the maximum protection, keep
Auto-Protect enabled and run LiveUpdate regularly to ensure that you have
the most recent virus definitions.

Please help, i don't know what's happening to Microsoft Outlook Express.
I
have confirmed to my internet provider that the connection is working
well,
they told me that the problem is probably with the Outlook Express. When
I
send an email, it seems that everything's ok because the email sent was
moved to sent folders. However, when I check with the receipient if
whether
they receive my emails, it was not received. I have tried it many times
but
the problem is still there. How come my email was moved to sent folder
when
it was not really sent anyway? Would appreciate your help. Thank you so
much and God bless!
