OK. I can access access port 110, but when I try to send mail from this address to michael@xxxxxxxxxxxxxxxx (my primary email address under my domain) the mail gets returned with this error: Each of the following recipients was rejected by a remote mail server. The reasons given by the server are included to help you determine why each recipient was rejected. Recipient: <michael@xxxxxxxxxxxxxxxx> Reason: 5.7.1 <michael@xxxxxxxxxxxxxxxx>... Relaying denied. Proper authentication required. Also, whenever I try to send email from michael@xxxxxxxxxxxxxxxx I get this error: Unable to authenticate to SMTP server. Bad authentication response from server. Please enter the SMTP password for michael@xxxxxxxxxxxxxxxxxxxxx I changed the password in the text box to the password I use on the client PC, but it won't accept it. Mail worked just fine on my server PC (until it went down due to hardware problems), which was running RH9. I made nightly backups of the /etc directory on the server PC. Then I backed up /etc/mail on my client PC (which runs Fedora Core 1) and extracted the server PC's backed up /etc/mail files into my client's /etc/mail. What am I doing wrong? Can anyone help me with this? -Michael Sullivan-
