Need to block certain mail user on Fedora 2

mcsmit · 03-20-2006, 04:27 AM

I'm using Redhat Linux Fedora 2. We have our own domain. The users at head office can send mail anywhere and receive from anywhere,taht's fine. But I wan't set up mail for the branches, I already set up their e-mail addresses and users but haven't installed at the branches yet. I want to block them them from sending mail anywhere else than out own domain, basically head office. eg: they must only be able to send mail to user@mydomain.com no where else. Please help. I'm using Sendmail.

What mail server are you using?
If it's Postfix, just set up some transport rules to limit outgoing mails.

I also replied to a post similar to yours, quite recently. Search around on the forum and you will find it.

I'm using sendmail.

Excuse my silly questions. I know Unix and am new to Linux especially the GUI. How do you set up transport rules?

A little forum searchin' on the Newbie forum showed revealed my earlier post, that contained the
following URL. Maybe that site can help you too.

As for sendmail configuration, I'm no expert either, so I can't help you with that.

Did'nt help.

I'm not sure if I am putting clearly what I want.

Let's say I have two users: User1 and User2

User1@mydomain.com can send e-mail anywhere but I want user2@mydomain.com to only be able to sendmail to anyone@mydomain.com and nowhere else. How do I do that.

I hace got a total of 22 User whom I want to set up to only send mail to anyone@mydomain.com

the rest of the user can send anywhere.
