fabrice -> Auto forward Exch 2k3 and MSEC (13.Jun.2008 10:11:32 AM)
Hello, one of my customer uses the Exchange 2003 auto forward fonctionnality to copy his mails to his gmail address. He has a rule on MSEC which automatically delete the mails with the [SPAM] keyword in the subject for outbound emails. It works when he makes a try from his outlook. The problem is when the mail is forwarded to gmail, the headers are not changed from the original mail. It seems that the "Return-Path:" is the original sender adress (foo@onedomain.com) and so MSEC can't delete it because onedomaine.com is not in the internal emails domain. We tried to add "onedomain.com" in the internal mail domain list and the mail was deleted so i think the problem is there. Does somebody have a solution ? Thanks

fabrice, I have attempted to get this working on my side as well and was unable to do so. When the message is forwarded out via the Exchange forward the message being sent out appears to go out from the user that sent it in. If I were to send a message to this user on your domain the forward would then send the message out as from gfi.com to gmail.com. This rule would have to have every possible domain that would be sent to you configured in your local domains configuration.

John, thanks for your answer. So there is no possible solution ? A way to tell Exchange to send the forwarded emails with the real sender address and not the original sender one ? Or a way to tell Mail Security to apply the rule for every mail sent by the organization, even if the sender domain name is not included in the local domain list ? Thanks for your help.

fabrice, I'm not familiar with a way to force Exchange to send the messages out under your local domain instead of the original domain. I've never seen this done but that does not make it impossible to do. GFI MailSecurity will only scan messages for domains that are listed in the local domain list. There is not going to be a way around this.
