I'm using VersaMail for the palm treo 650, and being pretty sure it was
the client now, dug into google and found someone with the same issue.
I'm now 99% sure that the problem lies with versamail rather than
postfix or dovecot.  Apparently PLAIN auth does not work but LOGIN does
work correctly.  OT can someone point me to a comparison/summary of
LOGIN versus PLAIN and whether I would be able to disable plain without
causing too many issues with other clients?  I did put a support request
in with palm so hopefully it will get fixed (ha ha :P)

Thanks,
Jonathan
