How to ask the IMAP server if new mail has arrived

How to ask the IMAP server if new mail has arrived

[Denys Duchier]

On to puzzle number 2.

Can someone come up with a handy function that asks the IMAP server if
any new mail has arrived, and returns the appropriate boolean.  Then I
could just use that to e.g. redefine display-time-file-nonempty-p to
get the desired Mail warning in the mode line.

Thanks,

Define "new mail has arrived". In IMAP, all mailboxes can receive
mail, so a proper check would be as time consuming as pressing `g'.

OTOH I guess this would work if you receive mail in "INBOX" on a
nnimap server with a empty virtual server name. It wouldn't re-open a
closed server though.

(defun jas-unseen-mail-in-inbox-p
  (let ((buf (nnimap-get-server-buffer "")))
    (and (imap-opened buf) 
	 (> (imap-mailbox-status "INBOX" 'unseen buf)))))

Um, I forgot a `0' for the `>' comparison to work..

(defun jas-unseen-mail-in-inbox-p
  (let ((buf (nnimap-get-server-buffer "")))
    (and (imap-opened buf) 
	 (> (imap-mailbox-status "INBOX" 'unseen buf) 0))))

Really appreciate the trailblazing your going through in converting to
IMAP. I fully intend to follow, but I'm happy to learn by seeing what
happens to you first.

There are probably others, and with the discussion about incorporating
imap documentation, are you taking any notes about converting from
nnfolders to imap? Worthwhile I think.

I have (partly) converted to IMAP a while ago.  I do the following:

(1) `G m' to create the new nnimap group.
(2) `G e' to edit the select method from (nnimap "") to "nnimap:".  (I
    think this happens automatically in the newest nnimap.)
(3) Use `B c' to copy all articles from nnml group to nnimap group.
(4) Check that articles arrived in nnimap group.
(5) Delete nnml group if check was successful.

It's quite a few keys to press but I didn't try to make it more automatic.

This helped improving the nnimap groups update speed a lot!!!

Thank you Kai.
