I always have ignored turning off the firewall; it is not hard in Gnome
to alter basic firewall behaviour and allow for ports like 576 (or
whatever that SMTP port is; not looking it up right now).
In the past, turning selinux to permissive was my first step in setup,
followed by moving SSH's port. Now I leave it as is and learn how to use
semanage.
