What is your idea (Postfix Update)
« on: February 20, 2020, 11:47:56 AM »
They have been trying to spam with different addresses from my server for 3 days.
Also, if I don't use a spam gateway, my ip addresses would be blacklisted.
Spam email cannot be escaped via spam gateway BUT...
How is spam trying to send spam with a different email address from my server? where is it open i couldn't find it..
anyways....

this came to my mind... this update. Was this spam problem due to postfix...
have you had problems like me? What do you think about this subject..

you need to read mail server logs, any system admin can detect spam source.
Also, there are several instructions about spam detecting on the cwp wiki.

this is not a complete log for the email, you should check all lines related to the email causing an issue
