After I hit send I came up with the solution. On the IMS there is a delivery restriction tab, if I add the users that aren't allowed to send outbound e-mail to the tab (or add a DL to the tab and the users to the DL) my problem is solved.

I'm pushing the idea of [EMAIL PROTECTED] so they can receive SMTP e-mails from the inside world. As it happens the sending program on the AS/400 simply connects to port 25 on the Exchange box so there is no need for MX records, we just told IMS that .internal should be routed <inbound>. The only down side is that users can still send e-mail. We can't disable all outbound SMTP on the server since there are some users that are allowed "real" addresses. When we presented our idea of "invalid" smtp addresses the response we got was "we can't give these users access to the internet" which isn't exactly what we are suggesting so I think it's time to thwap a customer or two. If someone could suggest an idea to prevent these users with invalid SMTP address from SENDING to the net while allowing users with valid SMTP to send we'd be all set, but I appreciate all the help I've received so far. May everyone have a happy and healthy holiday! -Walden ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 [EMAIL PROTECTED] http://www.TechSoftInc.com -----Original Message----- From: Peter Johnson [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 18, 2001 02:12 To: Exchange Discussions Subject: RE: Allowing internal SMTP but not external Hi Walden How about this as solution?? 1.) Remove the valid internet addresses from the users. 2.) Create invalid, from the perspective of the Internet, addresses for the users who need to get the mail from the AS400. Route this address as inbound. 3.) Configure the SMTP service on the AS 400 to deliver mail to the invalid address directly to the IMS of the Exchange server. 4.) Configure the IMS on Exchange to deliver replies directly to the IMS. The only issue that I can see is that these users will still be able to send mail out but will not receive replies since they don't have valid SMTP addresses.

Leverich [mailto:[EMAIL PROTECTED]] Sent: 17 December 2001 23:41 To: Exchange Discussions Subject: Allowing internal SMTP but not external OK, I think I know the answer to this, but I told a customer I'd ask. I have a customer that wants to limit users from receiving email from the internet. No problem, remove the SMTP address and they won't be able to send/receive SMTP mail. However, now they have a requirement for these users to receive SMTP mail from an internal machine (AS/400 sending e-mail to local users). Short of going to the SMTP proxy (Firewall-1) and saying drop messages for user1 and user2 and user3 etc. there is no way I can see of preventing external SMTP mail while allowing internal SMTP mail. Did I miss something? -Walden ------------ Walden H Leverich III President Tech Software (516)627-3800 x11 [EMAIL PROTECTED] http://www.TechSoftInc.com _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] "This e-mail may contain confidential information and may be legally privileged and is intended only for the person to whom it is addressed.
