I just got an email bounce - reason;
The sending IP (220.127.116.11) is listed on https://spamrl.com as a source of dictionary attacks.
The first thing I did was run a check on mxmailbox.com which shows my server as clean from all sites checked.
I wonder what the best way is of checking my system to see if it is commiting these dictionary attacks.
My system it somewhat older;
FreeBSD 3s1.com 9.3-RELEASE FreeBSD 9.3-RELEASE #0
Any pointers would be helpful.
