Hi, > Mike, Is this in an Exchange 2003 environment or Exchange 2000 > environment ? Exchange 2003. Works great, I sent an email from my AOL account to my Gmail account through the Exchange server. However, the bad news is: still needs CALs. Contacts do not need CALs as long as the email address is outside the exchange server's domain name space. That's not so here. oh well ... The solution I am looking at now is to set up a second mailserver (a Linux mailserver) and use separate domain names for the external users and internal users and forward all Exchange users to the exchange server subdomain and all forwarded users can be handled directly by the Linux server. Yukky but the alternative is too expensive for the client. Mike
