The command that caused the problem:

511 UID FETCH * UID

(copying emacs-devel regarding the maintenance issue)

Simon Josefsson hasn't replied to my pings, so I think he may not be
available for imap.el support.  Simon, please let us know if that's not
the case.

I'm willing to dig further and maybe support imap.el if no one else
wants it, but honestly the IMAP RFCs are unpleasant and annoy me, so I
need a better explanation of the protocol.  Google was not helpful.  Can
anyone suggest an IMAP primer I can read?  I'm interested in the actual
protocol, so the more concrete the examples, the better.

Thanks

Hi!  Sorry for not responding, I have been busy with other things, and I
don't have much time to work on (nn)imap.el any more.  I have time to
review concrete patches, but little time to help debug problems with
some servers.

However, the recently installed patch for Gnus is definitely the wrong
thing:

-	  (imap-fetch "1,*" "UID" nil 'nouidfetch)
+	  (imap-fetch "1:*" "UID" nil 'nouidfetch)

This generates thousands and thousands of unnecessary lines of output,
such as:

669 FETCH 1:* UID
* 1 FETCH (UID 53159)
* 2 FETCH (UID 53160)
* 3 FETCH (UID 53161)
...
* 103915 FETCH (UID 157074)
* 103916 FETCH (UID 157075)
* 103917 FETCH (UID 157076)
669 OK Completed

That's about 2-3MB of output, and that was getting information for one
of my folders (I subscribe to maybe 100-150 folders..).

This slows down pressing 'g' on my server from sub-seconds to a very
long time (I pressed C-g after half a minute).

This is how the output should look like:

698 FETCH 1,* UID
* 1 FETCH (UID 53159)
* 103918 FETCH (UID 157077)
698 OK Completed

That's 89 bytes and takes ms's to transfer.

If you want this bug workaround in the code, please make it conditional
on some variable that is disabled by default.  I suggest documenting
that this may slow down things considerably.

I'm not aware of any, and I would agree that the RFC is unfriendly...
if you can't find any primer, just toggle imap-log and try to understand
the commands send by Gnus for each operation that is needed.  Read the
RFC for full explanations of some things.

Simon,

Can you suggest something better to fix this problem?  I'm sure that I'm
not the only user who will want to use Gnus with Exchange 2007.  This
fix, incorrect though it may be, does work.  Is there something other
IMAP command that will get data in the way Gnus needs to see it?

Does the fix work?  In another post you said it didn't help.

We can introduce a variable nnimap-enable-exchange-bug-workaround that
toggles the way the code works.  You can set that variable, if it indeed
solves your problem, and others can leave it at its disabled default
value.

Note that using the 1:* command over the 1,* command will generate
excessive traffic.  (For me, checking new mail jumped from a few kb's to
>10MB.)

Here is what I propose, if 1:* really solves the problem.  Please test
it, apply the patch and customize nnimap-enable-minmax-bug-workaround to
a non-nil value.

Simon,

I probably thought it wasn't working because of the performance issue
sue to the amount of data being transferred.  Yes, the bug fix _does_
work and I _am_ able get data from my Exchange server.  Unfortunately,
it is quite slow and, has some other bugs with moving  email betweeen
folders.

Ok, I have installed my proposed patch in gnus cvs.

You need to customize and enable nnimap-enable-minmax-bug-workaround to
use the slow behavior.

If I understand correctly, what this command is intended to do is to
retrieve the UID of the last and first messags in the mailbox.  If so,
would it not be possible to use a pair of FETCH commands instead?

Yes.

Perhaps, those with exchange servers could test this.  The patch would
then be.  Jake, does this patch (against latest CVS) also work for you?
If it works, it should definitely be faster than 1:* queries.

OK, I will try that.  I can take over imap.el and nnimap.el if no one
else wants to do it and Simon is OK with it, though I'm no IMAP expert.
