RE: POP3 client using another user's IMS SMTP address

[McCrary Earl Contr 411 FLTS/TSF]

No, the underlying SMTP address is the one for the displayed name.  Anyway,
I've come to find out it's just the nature of SMTP.

Well, for one thing, I don't think they do.  For another, the address itself
isn't being forged, it's the display name, isn't it?

If that's the case, then why would an ISP ever use Exchange as their Email
server?

I don't believe you can.

Subject: POP3 client using another user's IMS SMTP address


How can I prevent a POP3 email client from using another user's SMTP address
in the From: field of an email message?

Here's the situation:   When configuring a POP3 email client on a networked
connected workstation using a valid network user account;  I can configure
the POP3 client to use any users' Exchange container name as the username
(blank password) and once configured, send an email to the Exchange Server
IMS connector for delivery via SMTP.  The email arrives at the destination
with the "forged" user's address in the FROM field.

Is there some setting on the IMS connector to prevent this?
