Question Blocking access to mail from external ip

M

M3 Prestitichiari

New Pleskian
Goodmorning to all,

I've to allow login only on three ip addresses for security reasons, is it possible to block other ip from login to my mail server? I'm using Postfix/Dovecot on my server.
Thanks in advance for any help,
Domenico
 
install the plesk firewall extension and configure the imap and pop3 rules to allow only the three IPs
 
Thank you for your help but it's not working the way i need it to work... It effectively blocks all connection from clients that are out of the list but i'm still able to login on webmail service... can i block all type of login to the mail server? included those on webmail..
