I have installed Postfix on my server with DNS. I am not sure what information I should provide here so let me explain the setup and goals. I have SuSE Enterprise 9, Apache, Static IP address. In other words a hosted website/server. The goal is to also have this as a mail server. I am able to send emails to certain addresses like hotmail, but not others. I am also able to send to a local email address. I am not able to receive amything. In the failure header of trying to send to the postfix address: ********************************************** ** THIS IS A WARNING MESSAGE ONLY ** ** YOU DO NOT NEED TO RESEND YOUR MESSAGE ** ********************************************** The original message was received at Wed, 28 Dec 2005 08:09:37 -0600 (CST) from localhost [127.0.0.1] ----- Transcript of session follows ----- <sapient@hingedmind.com>...

Looks like the queue is trying to send email with the TO: "unknown"? This started when I uncommented the pop3b in the inetd config. I might add this is more activity than before.
