TLS issues

[slavaaaaaaaaaa]

I'm trying to get this to work on Gentoo. When built with gnutls useflag, it throws an error: "The TLS connection was non-properly terminated," which really seems to be a gnutls issue (even though it hasn't been mentioned for the current version) I then tried rebuilding mutt with ssl and -gnutls, and now after fetching mail it just errors "Connection to outlook.office365.com closed," followed by "Mailbox closed." I should mention that mutt successfully fetches hearders right before these errors. What am I missing?

Can you run Mutt in debug mode with mutt -d 3 (or a stronger debug level if you don't fear being overwhelmed by logs), then look at ~/.muttdebug0 what can cause this?
Alternatively you can set the environment variable GNUTLS_DEBUG_LEVEL if you feel like gnutls could be a suspect.

I'm experiencing some “Mailbox closed” messages too since the last few weeks, but it only happened after about 20 minutes because of an unreliable connection.

Overall, I feel like Mutt's IMAP code is not ready for the prime time, and maybe integrating with offlineimap could be a solution.

ork,

Tried debugging both with no good results. Today, however, my coworker and I got it down to these two lines in muttrc:

set imap_check_subscribed="yes"
set imap_list_subscribed="yes"

I don't know about you, but I had quite a few folders I've moved around all over the place.. Looks like that somehow broke things, since I get lines like these in muttdebug:

[2015-06-15 14:55:13] 6< a0034 NO INBOX/Todo doesn't exist.

That folder was moved out of Inbox, so looks like there's still some trace of it. Might want to leave some comments by those two lines saying it breaks for some.
