I have installed sendmail 8.12 in Redhat Linux enterprise server 3 update 7 with sasl v1. I was able to authenticate relaying users for other network.
But the real requiremet was I need to authenticate internal users also (users in the same mail domain ex. firstname.lastname@example.org
) when they send mail within internal domain (not relaying)
How can i make this possible, please can anyone suggest an option to do this.
