Has anyone ever implemented Microsoft's SMTP gateway for MS-Mail?
Both Microsoft and our mail people here swear that it is unbreakable, 
(nothing is unbreakable)
but I was wondering if anyone has ever implemented it or discovered any 
"holes". The machine sits on both our unprotected side to receive mail from 
the internet, translates the internet addresses to MS-Mail addresses, and 
shoots them off to our mail MTA. Since it is dual -homed, I do not feel 
comfortable, but do not have any real data to support my paranoid feeling. 
If anyone has seen any problems, or know of anything, I would appreciate 
hearing about it.
