 nnimap performs 'intial sync' on all mailboxes every time 'M-x gnus'
 is run
Date: Thu, 26 Jun 2014 00:08:52 +1000

I'm using nnimap, configured to use the Fastmail IMAP servers.  Every
time I do 'M-x gnus', nnimap performs an 'initial sync' of each mailbox,
downloading many MiB of data.

In addition to being very slow, this is probably irritating the folks at
Fastmail no end.

My gnus configuration is as follows:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(require 'gnus)

(setq user-mail-address "duncan <at> bayne.id.au")
(setq user-full-name "Duncan Bayne")

(setq gnus-select-method
      '(nnimap "duncan <at> bayne.id.au"
               (nnimap-address "mail.messagingengine.com")
               (nnimap-server-port 993)
               (nnimap-stream ssl)
               (nnimap-list-pattern ("INBOX" "INBOX.*"))))

(setq message-send-mail-function 'smtpmail-send-it
      smtpmail-starttls-credentials '(("mail.messagingengine.com" 587 nil nil))
      smtpmail-auth-credentials '(("mail.messagingengine.com" 587 "duncan <at> bayne.id.au" nil))
      smtpmail-default-smtp-server "mail.messagingengine.com"
      smtpmail-smtp-server "mail.messagingengine.com"

This was fixed around July last year. Updating either to the latest Gnus
release (http://git.gnus.org/cgit/gnus.git/snapshot/gnus-m0-11.zip) or
to the latest Emacs pretest (24.3.91) should fix your problem. If not,
please reopen this bug.

Subject: Still happens with Emacs 24.4
Date: Wed, 22 Oct 2014 12:57:12 +0200

I'm also seeing this issue on Solaris 11/x86 (i386-pc-solaris2.11): on
my workstation, it occured for the first time when switching from Emacs
24.3 to 24.4.  With a 100 Mbit/s connection to the IMAP server,
gnus/nnimap is barely usable.

The issue isn't new, though: on my Solaris 11/x86 laptop, it occured for
the first time when switching from Emacs 23.3 to 24.1, and in all
versions up to and including 24.4.  With slower network connectivity,
the Emacs 24 versions are completely unusable due to this bug, so I have
to stay at 23.3 there.

Any suggestions on how to further investigate this?  This bug is most
annoying.

Thanks.

	Rainer

I'm going to try to repro this tonight, with the latest Emacs and gnus,
and see if I can track down what's causing it.  I'm moving more and more
of my workflow into Emacs (I'm now an avid org-mode user) and this is
the 'last piece of the puzzle' for me.

If Gnus is doing the "initial sync" every time, then that means that
Gnus is not storing the fill IMAP data in the ~/.newsrc.eld file.

What does the `G E' data on one of these nnimap groups look like?
(`G E' is a group mode command.)

That sounds reasonable, as the file ~/.newsrc.eld doesn't exist.

If that file doesn't exist, then that's your problem.  Are you exiting
Gnus without saving anything?
