Karen, maybe you need to go back and carefully re-read all of the posts
regarding this subject.  Let me briefly recap for you:

Summary of my post reiterating what Kami was asking for (Sent: Monday,

=====
Eric, I think what Kami is saying is that someone from spammerville sends a
message to you at your IPSwitch e-mail address with a "From" address of
[EMAIL PROTECTED] and you receive the message because your account is
local, so SMTP Auth is not required.

So, he is asking why IMail cannot so a simple check of any "From" address
that claims to be from a local domain, and if the account does not exist and
is not an alias, then reject the message.  Sounds like it could be a nice
spam control feature.

Bill said what I was trying to say..

So obviously I know what Kami was asking for.  Sandy posted a follow-up
message that stated very clearly (Sent: Monday, September 22, 2003 10:04 AM

=====
IMail does perform this *exact* check if you use the open-relay option
"Relay  for  Local  Users." So not just theoretical to imply that the
check  could be done during the SMTP envelope in a future release
(as an option, not a mandate).
=====

Sandy was merely stating that most of the code necessary to do what Kami was
requesting is already built into IMail.  With a bit of tweaking it could
probably fairly easily be modified to support this new feature request.

Hopefully you are clear on this now...

Bill
