Well I seem to have the internet mail going to the SMTP gateway one the sunbox like I wanted it to (thanks to you guys). The problem now is that we are showing up with a stray character in the email address when someone replies to a message from someone on the Exchange server. In other words if I send an email to someone and they reply there is a space ' space in the address ie: bkendrick@'austincollege.edu . Although I think it may be a problem with the Sunbox I though I would post it here in case anyone here has seen this behavior before. Thanks Byron.
