I've been trying to figure this out by reading the internet, but can't find an answer.
From what I understand, if a BES user receives an email in their Exchange mailbox, then Exchange will send a UDP notification to the BES stating so.
Does the BES Messaging Agent then pull the message from the mailbox, or does Exchange push the message to the BES?
And, secondly, does anyone know what this UDP port number actually is?
Thanks in advance
