[Dovecot] question about dovecot imap outlook clients

[Joseph Norris]

Hello,

Well... thanks to the input of all of you I have my dovecot->ldap 
connection working for almost all of my clients, however...

on outlook, a message for certificates being trusted comes up, the user 
clicks yes and connection fails.

Questions:

Do I have to get an ssl certificate to make it work?  ( cost ouch!)
Is there a way around this using my own self-signed certificates?
Is there a cheaper ssl certificate service?

thanks
