Not sure if anyone has addressed this problem and if so, I apologize for the redundancy. I administer an IMail server for three domains, a collection of hospitals. One hospital flat out refuses to let us administer their users / domain and maintains their own Mail machine. Herein lies the problem, our machine accepts mail for Subdomain.domain.com without regard to valid address and fails several Spam Test. Log show results.

They are currently using a program, Postal Union for Microsoft Mail. Believe me, I've begged and pleaded and they still will not let me maintain their domain on my server. My current problem is this, how do I secure email passing thru IMail so we don't become the unsuspecting relay host for spam. I've place current restrictions on no more than 25 recipients per message but this still doesn't solve the problem. I also monitor the log files on a daily basis but I want to close the doors before the problems occurs.
