Unable to receive email on one of my accts, but able to on other

[Dana]

When I click on send/receive I get an error on one account, however I do
receive email for the other account.

Account: 'mail.bellsouth.net', Server: 'mail.bellsouth.net', Protocol:
POP3, Server Response: '-ERR login failed', Port: 110, Secure(SSL): No,
Server Error: 0x800CCC90, Error Number: 0x800CCC92

This happened all of a sudden as I was using my email account successfully,
so nothing was manually changed.

I forgot to include that before receiving the error, I am asked for a user
name and password which I have never been asked for before and when I enter
them, it still does not authorize. I receive the error only when I cancel
that user name request box.

Happens to a few and is a problem at the mail server end. Have you contacted
your e-mail provider?

You can test your password by logging in to webmail.
If that works, it proves you have the correct username and password.
One reason for it failing in Windows Mail is account corruption. One
thing you should try as a possible quick fix is to delete that corrupted
mail account, restart Windows Mail, then recreate that account.

If that doesn't fix it, more drastic measures will have to be taken.
Which antivirus are you running?
As a minimum, email scanning in the antivirus must be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

If turning off the email scanning function does not resolve your problem,
consider upgrading to Windows Live Mail, because it is less prone to
suffering bad effects from overly aggressive antivirus programs.

Email scanning in any antivirus must be disabled, for reasons
