The requirements are:

(1) Clients running on given hosts (IP addresses) can send messages
anywhere in the world. The number of such privileged hosts (IP
addresses) is very small.

(2) All other clients can send messages only to addresses at given
domains. The number of such privileged destination domains is very
small too.

Is it possible to enforce such rules using Sendmail for NT Build 101
8.9.3/NT-8.9.3?

If yes, then how exactly can it be done? (I am less than a novice with
Sendmail, so if this can be done with some simple code in some
configuration file, I would really, really appreciate detailed
instructions.)

Thank you,
Yarik.

Dunno, that would be something to ask Sendmail. If they have a user forum,
you'd probably get an intelligent response; this forum is for the Exchange
"Windows Messaging" client that shipped with NT. Sendmail is a third party
application and you likely won't find any experts here; I'm certainly not,
I've never used the product.

Hi Hal,

I do understand that this forum is not the best one for my question.
It's just the problem is very pressing, so I cross-posted to all
newsgroups where I saw any discussions of "Sendmail for NT".

In any case, I apologize for any inconveniences that my cross-post may
have caused.

Best regards,
Yarik.

No inconvenience at all, my concern was getting you good help.
