Is it possible to enable a mailbox user account to use both the default POP3
virtual server and the newly created secure POP3 server. In other words,
could a user use the default POP3 server to send email generally to everybody
and use the secure POP3 server to send encrypted email over a SSL connection
to a small group of people that are also enabled to use this secure pop3
server. If possible, how could this be set up?
Finally, as regards to creating a secure POP3 virtual server for PKI
implementation, is it necessary to install a signing certificate on the
client PC from a CA in order to encrypt messages using Outlook?; and must
this same certificate be copied or exported to the recepient for the purposes
of decryption? In the http://support.microsoft.com/kb/319273 article it
mentions that the secure password authentication check box should be enabled
in the client PC. Does this mean that everytime the client user
authenticates with the secure POP3 server, it must enter its domain
user/password credentials for the mailbox? Alternatively, could a SSL
certificate be used instead for authenticating rather than having to enable
secure password authentication? - thereby eliminating the need to enter
domain credentials everytime while still maintaining security at the client
authentication stage.
I would appreciate any response to my questions on securing a pop3 virtual
server.
Thanks
