Allowing authenticated external users to relay mails from anywhere through internal sendmail
Posted on 2000-05-05
I have setup a sendmail (8.10.0) on a Redhat Linux 6.1 machine. Since anti-relay is by default on, users cannot send mails through the company sendmail server from home or any other places.
I suppose the best way to allow that is to use some kind of authentication mechanism according to user address name before the user can relay their mails. Anyone knows how that can be done. Is SMTP AUTH a good way? If so, how is it setup?
