I updated mutt and it seems that the PLAIN method is now available but,
for a reason that is not logged when mutt is run with -d2, it is tried
but fails:
imap_authenticate: Using any available method.
imap_auth_gsasl: using mech PLAIN
Authentification (PLAIN)...
4> a0001 AUTHENTICATE PLAIN [long-string]
4< a0001 NO AUTHENTICATE failed.
imap_auth_gsasl: PLAIN failed
I did try fetchmail but it segfaulted. I don't know how I should proceed
from here. Any suggestion welcome.
Sébastien.
