Good evening

Thank you for taking the time to view my message. Please can you answer the below if possible?

A) Can i turn on the firewall on CentOS 8? Will it break anything?
$ sudo systemctl start firewalld
$ sudo systemctl enable firewalld

B) Can i secure the password files?
$ sudo chattr +i /etc/passwd
$ sudo chattr +i /etc/shadow

C) I checked the forums and you mentioned some time ago about adding spam assassin spoof plugin. Is this active now? How do i add it and enable it?

Kind regards
Edward

A) Yes, just make sure you allow at least tcp ports 22,25,80,443,587 where needed.

B) Yes, that should be fine.

C) FromNameSpoof? You can enable that plugin in /etc/mail/spamassassin/v342.pre.

Thanks for the response Shawn

I configured point A and B and see the line in that file for spam assassin was already uncommented. All running well.

Kind Regards
Edward
