Data Transport in the Blackberry Environment

Hi,

     I have a question about the data transport in the BES, BIS and ISP environment. If I understand correctly data transport for the BES, BIS and ISP on the application layer as HTTP or HTTPS and routed through network layer on the Internet as IP.
Where in the data transport does SMTP come into play? and MAPI?
What if a user wanted to get emails from Hotmail and use POP3 SSL, how is the data transported in the BES,BIS and ISP environment? If they use POP3 SSL, Are they still using HTTPS?
I need to have a clear understanding on how the data is transported and the security issues involved.

Thanks, MissyMadi

For the BES:
This uses the mapi to connect to the mailbox but this is only used in your internal network.
To the outside only port 3101 is used to connect to the RIM servers.
As for SMTP, this is used by your exchange environment and not directly with the BES.

Hi,

Thanks for the info.
In an Exchange environment, is SMTP only internal?
What if a user wanted to get emails from Hotmail and use POP3 SSL, how is the data transported in the BES,BIS and ISP environment? If they use POP3 SSL, Are they still using HTTPS?
I'm looking for the specific data transport route and the protocols, for example:
In a BES environment the data travels the mail server(SMTP)  > BES(TCP/IP) > Firewall(3101)  > Internet (IP) > NOCs(what protocol is the data being transported?) > Blackberry device(AES).

In BIS environment  accessing HotMail (POP3) what is the data transport path and the protocols for accessing HotMail(POP3) with and without a BES?
