Disable Outbound Mail possible?

Post by Sephiroth » 10 Oct 2019 13:20

I was wondering if I could disable the outbound in efa, as I'm using a different smarthost in Exchange.
I got the feeling, that efa might get used as a relay, and am not sure how to check, or disable this.

If I understand you correctly, then there is nothing you need to do. Since EFA is not used for outbound, it won't be used for outbound.

If EFA is being used as a relay by your internal users, I suggest you find out why your internal users are doing that.

If you're really paranoid, you can set your firewall rules to block all incoming smtp requests from your internal users.
