Based upon this description, you'd be better off using the IIS stmp service configured to forward mail to your production IMS on the box instead of an "invisible imc" . I'm not sure if I completely understand the situation, but are you saying that you have an open relay that is accessible via the internet and secured only by it not being published? If so, I highly suggest that you rethink your strategy, as security by obscurity is not a good practice. I'm a big fan of authenticated relay via SMTP using TLS for encryption, but there are plenty of caveats to that approach too.

We have a group of users that are 100% mobile and they don't login to any RAS here so they login to local AT&T ISP depending on what state/city they are in. Based on this we had to deploy a 'invisible SMTP' server just these people because we had to have our registered SMTP server be relay secure. We couldn't do authentication or specific IP's and block relaying because the group of users would only be able to submit email to people in the site and not be able to send email back out to the internet. I brought the original problem to this list over a year ago and with much talk the idea of the invisible SMTP was the solution. The group of users hates the OWA unfortunately. I think it was actually ed that may have suggested it. The desired effect is to have a user submit a email to the IMS and wether that person is internal or one of our mobile users, that email would reroute to the registered SMTP and never leave via the invisible SMTP. Does that all make sense? Hope so. e- -----Original Message----- From: Chris Scharff [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 11, 2002 4:41 PM To: Exchange Discussions Subject: RE: IMS Costs Cost is one of the last things evaluated in choosing a gateway. Since an outbound IMS doesn't fail over, what's the design goal of having an "invisible" SMTP server? And what is the desired behavior in comparison to what you are currently seeing? -----Original Message----- From: Hansen, Eric [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 11, 2002 2:05 PM To: Exchange Discussions Subject: IMS Costs Hi Exch 5.5 sp4 on win2k sp2 What would make internet email ignore( apparently )cost values of the IMS? I have two IMS on separate machines, one is our registered mail server the other is a invisible SMTP server. The cost of the registered is 1 and the cost of the invisible is 100. But I'm seeing email que up on the invisible server. The invisible server is our mailbox server, could that have something to do with it? e- _________________________________________________________________ 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] _________________________________________________________________ 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] _________________________________________________________________ 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] ====================================================================================== NOTICE - This communication may contain confidential and privileged information that is for the sole use of the intended recipient.
