Mail Server IP Address has been blocked
« on: January 05, 2017, 07:45:06 AM »
Hello, i need help ..

I read spam email and ip address i in the block by google & yahoo, but not by email other hosting providers.

I've read the guide at: http://wiki.centos-webpanel.com/how-to-resolve-spamming-issue-with-postfix

I had to change the password, which I think it is quite safe.

anyone ever encountered?
please share here, thanks
