Hello,
I wanted to ask for help to see if I can solve a problem.
First, I apologize for my English
We are receiving a lot of spam; The spam mails almost always follow the same pattern, but change the subject, message body, recipients and domain from which "supposedly" sent.
In the server runs with: Centos 7 Plesk 12.5 and Postfix.
I activated the antispam protection based on SPF, at the server level.
But spam still slipping through more than taste different options SPF spam protection....
Can you help me set up to prevent spam?
