No one can send messages to these domains when using my mail server. Could you tell me the commands to test this? I know how to telnet to their mail server to test the connection, but I am not familiar with using telnet beyond that point. Thanks. -----Original Message----- From: redhat-list-admin@xxxxxxxxxx [mailto:redhat-list-admin@xxxxxxxxxx] On Behalf Of MKlinke Sent: Saturday, January 03, 2004 1:19 PM To: redhat-list@xxxxxxxxxx Subject: Re: Sendmail configuration problem?

Try telnetting directly into the remote mail server and issue a set of commands to manually send them a test message and see if you get the same problem.
