Mail Queue Manager Issues

[bigbankclub]

I noticed today there is a load - I mean 1000's of emails filling in the Mail Queue.

How can i id the issue. Anyway to block all emails from sending that are not real emails per my domain.

It's sending from random names per my domain and sending to who knows if these emails are real or just attempts.

This the report per one of the emails. I replaced my personal details with xxxxxxx's and filled in some details in plain English.

But what should I be doing to prevent spam and relay services??

Mail Control Data:

Hello,

Try searching for the message in /var/log/exim_mainlog to see if you can determine the source of the messages. EX:

exigrep user@domain /var/log/exim_mainlog
