Can I set up Exchange to kick back Emails that aren't in the Active Directory?

Posted on 2007-10-11

Currently if someone sends an Email to our company, it doesn't matter who it's addressed to. It still goes through the system, GFI Catches it and sends it to the Spam Trap.

This leads to a large spam trap

For example I could send an email adressed to and it will get caught by the spam trap and sit in the spam trap mail box.

Is there anyway I can set this up to be sent back to the sender because that Email doesn't exist? Based off the Users I have in the Active Directory?

Thank you

    What version of GFI are you running?  Microsoft Exchange does what you want by default, but it sounds like GFI has a custom SMTP event which catches every email before Exchange bounces it.

    If so, you may need to check out their documentation or have a chat with them about it, as I'm sure it's not an insurmountable problem.
