The *ONLY* thing from your "wishlist" *untested* in sendmail.cf is using more than one set of authentication credentials for one smart host based on sending user. As you read in the other thread I think it can be done by sendmail.cf too.

BTW I can get a DNS domain "free of charge" e.g. at dyndns.org

P.S. I have "discontinued" the official page of "smart table". [ routing based on envelope sender email address ]
