Resolution
The process of notifying a client that there is a new mail is initiated by the Post Office agent (POA) using UDP. The POA sends from the client port (default 1677) a UDP packet to the client (high port), telling that there is a new event. Also the client will send a keep-alive via UDP to the POA client port (default 1677).
To solve this issue, UDP should be allowed via the firewall.
