Mail Delivery Unauthoprized

Every now and then I’ll get a Mail Delivery Error" back for an address that I never even sent mail to in the first place.

Shouldn’t the firewall block unauthorized outgoing mail?

How can I check this and or correct it?

You are maybe not the “culprit”, someone might have usurpated your mail adress.

In order to check, you need to shift, in the firewall security strategy, your mail client from “mail client” to “custom” and write an asking rule TCP out, ports 25 and 110, also specify the ip or range of ip of your mail provider if known.

I’m not at all sure I understand what you are saying I might try…
