Tutorial: Using Zones - mailserver with security ports

hello there,

I wanna say thank You to Simon Edwards for this realy nice and "good to 
read" Guarddog Handbook .
Nevertheless I failed in the "Tutorial: Using Zones", because I didn't 
realize, that my client is connecting to my ISP via Port 465 
(mail.gmx.net) - which seems not to be covered by the standard mail 
protocolls.
https://www.grc.com/PortDataHelp.htm named this port "urd", which I 
couldn't find in the guarddog list. (?)
So I decided, to make a "user defined protocoll".
May it would be a good idea, to make a hint in this Handbook section 
about checking the ports.

Nevertheless, Your interface & handbook helps me very much to get rid of 
  my "fear" about this iptables stuff -- thank you!!
