Internal POP Access  

---

 
We have to give our internal users POP access to the mailserver.  This rule has to go before the  Block DMZ rule, or our internal users would never be able to access the mailserver. NOTE: A more advance setup would be to have a secondary mail server on the internal network pull the mail from the external server at specified intervals. Internal users would then get their mail from the internal mail server. However, detailing such a setup is beyond the scope of this paper (however, I may have to change the scope of this paper if I keep getting hate mail about the mailserver setup pictured here :)
