Block emails sent in bulk with other email SPAM

[keldnner]

Good morning, I had serious with one of my clients who had part of his emails hacked and used to use SPAM problems.

First I have on my firewall blocked most of the IPS Countries that are not necessary to be a more local service, but it did an update that did not turn on again and it was where everything went wrong.

The client was invaded by one of these countries and used for SPAM with the domain using a mask to email another email either.

Why do not fully know the panel, I wonder if there is any option to block the change of email sending, being sent must like the authenticator without defining a possible change in who is sending.

I would also like to know if anyone has other tools or tips to help in this type of invasion and mass mailing.

What cPanel provides documentation is already running, so that part of SMTP Protection I have disabled since I'm using CSF as SMTP blocking.

The limitation is per hour for 200, do not know what else to add to the server security, I'm putting together a script to check the number of queued mail to notify via sms or notifications on smartphones, I believe that is one of the only things that can do other settings

Note that if an email account was hacked, then updating it's password to a strong one is likely the best way to prevent the issue from happening again.

Thank you.
