smtp connector for internal email
Hi i have an issue with spoofed email with email addresses in my own domain. i have 1 exchange server 2003 and a server is use internally to relay mail. i have a virtual server setup and 1 smtp connector for the server i use to email. the issue that has occured is that when i added *.domain.com to my filtering to disallow spoofed email i wasn't allowed to send out email from my domain from my server used to relay mail. I then went and created a connector for local email and a connector for external email. now my issue is that although i can send email from my relay server in house now. email with from internal addresses in the from field cannot go out the external server i get a 5.7 error. is there a way that i can set up the exchange server to allow email from my internal server that relays to go out externally even though it will have an address with *.domain.com in the from field? please advise. j

You've marked this as a comment. Please click change-type and select question. SPF records would prevent this. Identify both of your servers in an SPF record and configure your exchange server to reject messages failing the validation. ref: http://www.msexchange.org/tutorials/Configuring-enabling-Sender-ID-filtering-Exchange-2003-SP2.html Mike Crowley Check out My Blog!
