Uhhh... when eltrasimaco asked you to do a telnet, he meant to the MTA/SMTP relay that will be delivering your mail, also we would need a part of your /var/log/maillog that shows an attempt to relay mail to someone external to the localhost.

It would be a really good idea to speak to your exchange/mail administrator, he should be able to help you sort this out in minutes.

Hi,

I put the maillog in a attached file.

Thanks for your help.

Raph

That does not really help us, help you. from a quick glance it looks like the messages are being bounced by the SMTP relay.

Speak to your email administrator. He is a whimsical god of message delivery who can help you.
