[TriLUG] wireless email client

[Jason Tower]

i have a client who wants to purchase a blackberry or treo to use with 
their email system, which runs on their linux server (postfix and 
courier-imap).  does anyone have first-hand experience with this kind 
of setup?  do those units have good imap and smtp-auth support?  
they're already using server-side email with an imap client (lookout) 
in the office and squirrelmail on the outside.
