i know there are a variety of mail clients that support IMAP and SSL. i want to know if any of them support the installation of a client cert to uniquely identify the treo to the IMAP server so that the server can reject connection attempts from j. random bad-guy. in particular, can i install a self-signed cert cut from a CA running on my own box (e.g. a linux box running openSSL and the CMU cyrus IMAP server)?
