HI All,

Quick question on whether I have to configure Fail2ban to monitor Port 587. Should I add the value '587' to the Postfix section of Jail.local? Or does the value 'smtp' already cover it?

Snippet from Jail.local:
action = iptables-multiport[name=postfix, port="http,https,smtp,submission,pop3,pop3s,imap,imaps,sieve", protocol=tcp]

Thanks!
