I can't send any message from my imap account. From watching smtp traffic it looks like n9 tries to use BURL extension when talking to my smtp server, server which don't support it and don't publish it in its capabilities list. My guess is that email client have buggy code similar to http://meego.gitorious.org/meego-mid...t.cpp#line1125 where it check if imap or smtp server is capable of using BURL, but not if both flags are set simultaneously.
