While the Xi repositories are meant for testing to begin with, the 
.patched repositories are probably even more volatile as these include 
my personal patches against Dovecot (in this case 
http://hg.rename-it.nl/dovecot-2.2-patches/file/tip). I deliberately do 
not refer to these repositories in the wiki documentation, as these 
don't have 'vanilla' Dovecot packages. So, don't use these if you're 
looking for the latest official (yet unreleased) Dovecot revision.

Before, code for doing client side (PLAIN) SASL login (e.g. for imapc) 
was spread and duplicated at multiple locations in Dovecot code. This 
change puts it at a single spot and makes it easily extensible with 
support for new mechanisms.

This was discussed a while ago on the mailing list:


The submission patch adds an example configuration, although I haven't 
updated that in a while. It is also possible that the submission server 
is not in a usable state right now.

Yes. If I am working on some new Dovecot feature, it's included in this

Trojita supports URLAUTH/BURL. There is no telnet procedure described 
that I know of anywhere, but you should be able to digest what you need 
from the relevant RFCs and the examples therein:

http://tools.ietf.org/html/rfc3501 (IMAP)
http://tools.ietf.org/html/rfc4467 (URLAUTH)
http://tools.ietf.org/html/rfc5321 (SMTP)
http://tools.ietf.org/html/rfc4954 (SMTP AUTH)
http://tools.ietf.org/html/rfc4467 (BURL)

It basically boils down to: login to IMAP (port 143), APPEND a message 
to one of your mailboxes, generate an URLAUTH for it using the 
GENURLAUTH command, login to SMTP submission (port 587), issue MAIL 
FROM: and RCPT TO: commands and finally send the message using the BURL 
command with the URLAUTH generated from IMAP.
