I check the recommandations in this link but everythink recommanded is ok.

i dont know if the last sentence in error "your acces to submit messages to this email system has been rejected" and "Unable to relay for user@sierracollege.edu" are caused by the same issu.

Thanks

David_226 I would recommend performing a tcpdump on the F5 to ensure that you are sending the message to the destination SMTP relay server as well as a capture on that server to ensure you are receiving the relay.
