After re-reading the problem I have to agree. I should have read the entire message. I missed the part about being able to receive internal smtp mail. This will only work if the users are located on the GC.

If you know the ugly fully-qualified-object-name-SMTP-address, you can send anyone SMTP mail. Period. There's no way in Exchange to block that. However, nobody need know that, and the address is so ugly that nobody would try to use it unless someone sent out mail from a mailbox that didn't have an SMTP address and that's what got used as the reply address. The best answer was already given, and that was to create an e-mail domain internally that's illegal (unroutable) on the Internet, such as [EMAIL PROTECTED] Ed Crowley MCSE+I MVP Tech Consultant Compaq Computer "There are seldom good technological solutions to behavioral problems." -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Monday, December 17, 2001 3:08 PM To: Exchange Discussions Subject: RE: Allowing internal SMTP but not external Hmm. Well there is an option on each mailbox that you can setup the mailbox so that they only receive mail from internal users. I thought this was what you were requesting. -----Original Message----- From: Walden H.

I'm still able to send, but I (obviously?) can't receive from the outside and that may be good enough.

[EMAIL PROTECTED] or something. Works with Exchange 2000 but you didn't mention if you were using E2k or 5.5. > -----Original Message----- > From: Walden H.
