Hello,
I've got someone sending out spam from my server and I suspect he is using address like mailnull@hostname to by-pass exim authentication. Is this possible?
I think addreses like postmaster@hostname, mailer-daemon@hostname, etc are used for this.
Is it possible to disallow users to use those addresses to send out email?
Also, I've seen spam coming out from a domain which does not exist in my server, how is this possible? It is always the same domain (AdminRobot@hyipreal.com). Is there any way to block email coming out of that address?
Thank you
