I'm using sendmail to send and receive mail. I am receving email just fine, but none of my email is being sent. There are no error messages after I hit send.
Everything was working fine yesterday. I haven't done anything to the mail server since then. I noticed there was a problem when the PHP mail command was taking a couple minutes to send a simple text message and then it was not even received. Any ideas on what to do?
Server: (Linux) Fedora Core 3
