Question Best solution to stop incoming spam in a plesk server

[SalvadorS]

Hello,

We are receiving a lot of spam in our servers in the last days/months. It seems that backlist like b.barracudacentral.org, bl.spamcop.net or zen.spamhaus.org does not stop the spam we received and spamassassin is good but a lot of spam is coming.

So I want to know what are you doing to stop the incoming spam in a plesk server.

Thanks a lot.

Regards

You can configure spam assasin better, more custom rules or private rules ( paid )

Try add more RBLs
Enable dkim check, dmarc check, SPF check with restricted options

If all that not help, you may buy any external extension to filtering spam or the last option add some external antispam system.

Protecting Against Spam

Spam (or junk mail) distracts you and can make you a victim of scammers, phishers, and other malicious actors.
