I am running Smartermail 15.5 on a Windows 2012 machine. My question to you is I was just black listed on Protected Sky but not sure how to tell where or who its coming from. I will post the email headers and stuff below. But when I search for firstname.lastname@example.org or email@example.com between Feb 7 and 15 both for delivery and smtp nothing is found. mail.gdishosting.com is my hosting domain I have smartermail using. Also what is funny is joycevanlines.com I don't host there email on my server just there website.
I tested my server to see if it is an open relay and it passed that it isn't. I took a look in the Spool to see if I see any large amount of mail but nothing is there.
I also setup Abuse Detection for Internal Spammer with Time Frame of 5 mins, Count 25 and Block Time 30 mins. But I have not gotten any notifications regarding it.
I don't know what/where else to look or do to see where spam is coming out of my server. Can someone please help me provide me a step by step on things/sugestions I could do? I want to catch and stop the spam so I can get off the blacklist.
My Server IP is: 18.104.22.168 and 22.214.171.124
Email Headers of One Spam Complaint that went to my data center:
