2k7 edge user smtp tls pop3

Hi,
iam planing to implenent a exchange 2007 front end (edge) server into our current 2003single backend environment. What will happen to our POP3/SMTP users who are currently connecting directly to our backendsever via SMTPS POP3S? Is there a way to let them connect to the Front End (Edge 2007) and redirect em to the backend? How will the user authentication occur with a front end for pop3/smtp users. The mail flow from internal outlook/exchange and owa user makes sense, but how to handle external user who are using pop3/smtp?

POP3 runs under the Client Access server role, you cannot provide POP3 services on an Edge Transport.

Simply put, the clients requiring POP3 and SMTP will have to connect to the server within the network. Ideally via a VPN tunnel. Otherwise perhaps consider RPC over HTTPS to permit then to connect to the Exchange Service?

Bear in mind that OWA will not run on the Edge Transport either. Edge Transport is not really similar to the Front-End setting for 2003.

These are the main tasks of the Edge Transport:

Content filtering
White listing (Safe Sender List Aggregation)
Connection and recipient filtering
Edge transport rules
