[PERDITION-USERS] Perdition config question

Hi there- I recently found perdition and it looks like a beautiful solution to my migration- moving users from one exchange server to another. Unfortunately, I think the config may be missing one option which would make perdition a full-time solution. What I'd like to do is use unencrypted connections to the back-end server and encrypted connections coming in. Looking at the ssl_mode options, there doesn't appear to be a none_outgoing, which is what I believe I want. Could someone enlighten me and let me know if I can do this with some different option, or if I can't do it? If it's not currently in there I might just be motivated enough to hack it in.... --Ross
