Re: Bug with referring articles (was: chasing mail threads)

Tassilo,

Thanks very much for your thorough reply; if we can solve this problem
it will make it possible for me to switch back to Gnus, which I would
dearly like to do.

Ah, very nice!

Sure.

Yes, I am.

Well, it never has in the past.  I can try again...

Nope, it doesn't work.  `A T' doesn't do anything interesting, and `^'
now inserts a pseudo-article (which is a new behavior since last time
I tried this, which was a while ago).

I think maybe that is correct.  In my case, I'm even willing to tell
it what folder to search in, but it looks like Gnus doesn't give me a
way to express that.  I tried using the nnimap-inbox option, but that
didn't seem to lead anywhere.

Thanks again
