Ok, so here we go:

No, I cannot find it there. I'll attach it to this mail.

Subject: [PATCH 3/3] * org-gnus.el (org-gnus-store-link): Don't error out if mail
has no or bogus Date: header.
* org-gnus.el (org-gnus-nnimap-query-article-no-from-file): Query
article number from file is nil by default.
The function function `nnimap-group-overview-filename' is gone in Gnus
devel. Subsequently enabling this feature by default will cause
org-gnus to fail on Emacs24.
Thanks for Matt Lundin for pointing this out.
* org-gnus.el (org-gnus-nnimap-query-article-no-from-file): New
customization variable.
(org-gnus-nnimap-cached-article-number): New function.
(org-gnus-follow-link): Try to fetch cached article number of
message-id.
Some IMAP servers (e.g. Courier) are slow when searching for a message
by its message id header field. Because article numbers in IMAP
mailboxes are persistent UIDs, we can try to look up the UID of a IMAP
message in Gnus' cache for the mailbox in question and skip the slow
search on the server.
The problem with slow server was reported by Sébastien Vauban and the
patch is based on the work of Tassilo Horn.
The attached patch suppresses a compiler warning in org-gnus.el
* lisp/org-gnus.el:
Suppress compiler warning by declaring outside function
nnimap-retrieve-headers-from-file.

Argh, stupid me! Here's a corrected patch.

Aren't overview file and NOV file synonyms?
Hm, anyway. In the Gnus docs I've found this paragraph:
,----[ (info "(gnus)IMAP") ]
| `nnimap-nov-is-evil'
| Never generate or use a local NOV database. Defaults to the value
| of `gnus-agent'.
|
| Using a NOV database usually makes header fetching much faster,
| but it uses the `UID SEARCH UID' command, which is very slow on
| some servers (notably some versions of Courier). Since the Gnus
| Agent caches the information in the NOV database without using the
| slow command, this variable defaults to true if the Agent is in
| use, and false otherwise.
`----
So maybe we're trying to replace one slow command with another slow
command. Especially, the fact that Courier is explicitly mentioned is a
bit frustrating. Well, let's try it out and see if it helps a bit.

This variable defaults to the value of `gnus-agent', so I assume the
agent has to be enabled (which is default), and most probably the IMAP
server has to be agentized as well. That can be done in the server
buffer (`^' in *Group*), and then:
,----[ (info "(gnus)Server Agent Commands") ]
| `J a'
| Add the current server to the list of servers covered by the Gnus
| Agent (`gnus-agent-add-server').

Tassilo
