Many of you are having problems with sending mail from your accounts. Here's the workaround:

Set your SMTP settings to a Gmail account:

smtp.gmail.com
Use Authentication "on"
username@gmail.com
password
465
SSL

You sent emails will still show it was sent from your POP account in your incoming server settings and replies will be delivered to that account not your Gmail. But you will have a copy of your sent email in your Gmail account which I think is pretty cool.
