My Psion 5mx is connected to the Internet via the built in TCP stack, and serial cable to a raspberry pi running a PPP server. The Psion message suite has an email client which will connect via POP3 and SMTP. I have added a plug in to also allow IMAP access.
There are few email providers who support unencrypted POP3 and SMTP access.
How could I connect the Psion email client to a secure SMTP or IMAP server?
Any solution is welcome, including another email client, an email server on the Pi end of the link or even, God forbid, Java.
