Showing threads with IMAP

Showing threads with IMAP

[Peter Davis]

Hi. I've just started really using Gnus for IMAP mail, and just joined
this group, so please forgive me if this is a tired old question that
just won't go away.

I'm reading email via IMAP from Fastmail.fm. I have (setq
gnus-fetch-old-headers t) set in my .gnus.el, but I never actually see
any previously read messages ... only the unread ones. Is there any way
to get this behavior with an IMAP server, so that I can see all the
previous messages in a thread that has new, unread messages?

Thanks! I'm sure I'll have more ignorant n00b questions later.

'A T' (gnus-summary-refer-thread) should do the trick.

'C-h f gnus-summary-refer-thread RET' for more info.

However, on an IMAP server it only works when the server uses the
agent (I just tried).

Also it didn't work on a message that didn't have a proper References
header (sent by Lookout using an MSExchange server).  Nothing
happened, presumably because dovecot didn't recognize the message as
belonging to a thread...?

Thank you, Steiner. 'A T' works on this server, but I was hoping to have
threads with unread messages automatically show up in the summary. I
suppose I could live with having to recall them explicitly with 'A T'.

Thank you.

This is a bit of a guess, but does setting gnus-build-sparse-threads to
'more do what you what?

Thanks, Eric, but it doesn't seem to have made much of a difference.

How about setting it to t? That tries to fill all the gaps.

Hmmm. Maybe. I do seem to be seeing a lot of earlier posts, marked 'Q'
in the summary buffer.

Thank you, Jorge.

Oops, I misread the docstring...

Thanks for all the help and suggestions, everyone. Setting
gnus-build-sparse-threads to t does seem to do what I was looking for,
but now opening a group takes too long. So I think I'll drop back to
*not* showing previously read messages in the thread, and using 'A T'
when I want to see the history.

Thanks!

Change the value to "some". It is much quicker:

,----
| gnus-build-sparse-threads is a variable defined in `gnus-sum.el'.
| Its value is some
| Original value was nil
| 
| Documentation:
| *If non-nil, fill in the gaps in threads.
| If `some', only fill in the gaps that are needed to tie loose threads
| together.  If `more', fill in all leaf nodes that Gnus can find.  If
| non-nil and non-`some', fill in all gaps that Gnus manages to guess
`----
