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.
