bug#8050: Gnus does not connect to my IMAP server any more


From: Stefan Monnier
Subject: bug#8050: Gnus does not connect to my IMAP server any more

User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux)

SM> - Also when I'm then asked for a password, the prompt says "Password for
SM> user foo, host bar" which is more verbose but not more clear than
SM> "Password for address@hidden" used in earlier Gnus.

I mostly care about nnimap for now because it's the only case I bumped
into, but I can't imagine why it would be better to use "user foo, host
bar" for the default, since all uses I can think of will want to
override it with the "address@hidden" syntax instead.

Yes.

Yes.  I *never* know that the password is good (maybe I'm
a pathologically poor typist, but I can't be the only one who's been
surprised a few times to see his password rejected even tho he thought
it was typed properly).

No, you misread: I'm talking about the prompt to save the password
(i.e. the one with y/n/N/e/?), not the prompt to read the password.

Yes, fixing the previous one might fix this one, I just know this also
needs to work right.

SM> - After refusing to save the password in authinfo.gpg, I get a message

Two things:
1- then make it look nice, like "Saved password for address@hidden into <file>".
   The current text really looks like debug output.
2- I just replied "n" before, so I did *not* want it saved (tho I do
   want it saved for the session), so it is not a rare event at all.
