[RoundCube Users] Outbound email fails via smtp

I've attempted to program all settings into our server for outbound email usage, but to no avail. Currently we're a Cyrus OS X server, with smtp, password authorization required for outbound sending of messages. Now, I get the %u/p parts, and I have it set to the proper smtp address... should I not just be using 'LOGIN' as the password protocal? I've essentially tried all, and none seem to work, I'm wondering if there's a different outbound preference I should put in there that I'm not seeing? Thanks all!

p.s. -- I second the archival request.
