Does Spamassassin work as filter matching only ?
Does it check sender is exist ?


If it work as filter matching, I would like to disable spamassassin.
( I see in cpanel login...it's only set as filter. )



How to make exim check the sender is exist before send or receive an email ?


Thank for advance.

Log into WHM, click on "Exim configuration editor" and make sure the sender verify option is enabled.
