imap setups

[Jonathan Hutchins]

We're having some trouble getting a MacBook Pro and a Palm Pre connected to a 
mailserver.  We're using plain-text password authenticatioport with ssl on 
port 993, and both systems complain of an ssl error.  I've installed the 
certificate on each device and told it to trust it.

Has anybody had problems like this with Mac Mail or Palm devices?  How did you 
solve it?  Does anybody know what the limitations on what kind of imap 
configuration will work with these?
