Distribution list SMTP questions - 2.Jul.2008 2:09:35 PM

Status: offline 		Hi,

I have a Distribution list that people sends to it from externally.  Recently that email address has been SPAMmed and I want to remove the SMTP address.  When I did that, no one internally can send to it.  I get undeliverables when trying to send it thru the GAL in Outlook.

I thought Distribution Lists can work without SMTP addresses if used internally by users.  Why would I need to have an SMTP address to get it to work?

TIA

Tom

But this doesn't solve my problem of getting spammed.  Those SPAM will still hit the Exchange server, no? 

I want to get rid of the SMTP addresses, is that possible?
