Email Authentication for Matrix

First, is Matrix using the PEAR Mail package to send mail for things like, triggers, custom forms, etc? If so, is it possible to configure it to use authentication?


I am using a trigger, which sends an email. This email needs to go to our entire campus, but in order to do that, I need to have it authenticate, so that our mail server will let me send it to our campus list. I see that there are settings for SMTP and authentication for the PEAR Mail package, so would it work to add the authentication lines somewhere?

Yes, it uses PEAR::Mail but no, we dont have any auth support in Matrix.

I notice it has been 11 years.
Any progress in supporting Email Authentication in Matrix?
