I can't speak for SIMS, but I have an app out (Baton Mail) that works as
a SMTP relay (it lets you add smtp authentication to mail clients that
don't support it).
In Baton Mail, I could add a check for a No UCE banner (assuming I am
looking strictly at the HELO or EHLO welcome message, and searching for
the keywords "no" and "uce"), the addition of that code would take me in
the range of 5 minutes to add. Maybe add another 5 minutes to do good
debugging on it (try it against different ways of saying no uce, to make
sure the keyword logic will pick it up)
Basically, "its too hard to impliment" is a BS excuse from anyone that
wrote their own SMTP server. However, it is much more excusable to tell
someone it is too hard to do, then to tell them the truth, they don't
want to because it will reduce the number of servers they can spam.
