[PERDITION-USERS] Connect a IMAP4S-Server from an IMAP4 client via perdition?

Hi! Is it possible to connect perdition to an IMAP4 server via SSL, while the client only uses an IMAP4 connection without encription? I do have the ssl-pem-file available, it is a self signed key and it is used at the moment for a stunnel-connection. I'd like to remove the stunnel. At the moment the setup is like: client (no encription) -> perdition (no encription) -> stunnel (ssl) -> imap-server I'd like to have client (no encription) -> perdition (ssl) -> imap-server (ssl-only) Which ssl-options do I have to set to make it work? -- Thomas
