Hello,
The attached patch introduces a new server variable,
nnimap-hide-deleted. If non-nil, articles with the IMAP \Deleted flag
will not be included in Summary buffers.
This is intended to increase operability with other IMAP mailreaders and
the new 'never value for nnimap-expunge (see patch in bug 20670).
Thanks for considering.
Best,
-Nikolaus

Hi Nikolaus,
I am in no way qualified to speak on behalf of Gnus and its developers,
but I did want to say thank you very much for these patches -- it will
be great to see Gnus gradually mature as an IMAP client. The development
of Gnus seems to go by fits and starts, as people have time to devote to
it, particular for relatively deep-plumbing areas like this, so it's
possible you won't get much response for a while -- don't be
discouraged! I'm on the road with a temporary computer now, but will be
happy to run your patches once I'm back home, and report any
problems/comments.
Thanks!
Eric

Hello,
The previous patch did not take into account that an IMAP server is free
to send the UID, FLAGS and RFC822.SIZE response data items in arbitrary
order. This has been fixed in this version of the patch.
Best,

The first line of a doc string should be a complete sentence.
Andreas.

Hm... won't this make Gnus think that the articles doesn't exist? So
they'll end up in the "unexist tracking" list? I don't think that's
correct...
I think it would be better to just convey the information up to the Gnus
layer, and then Gnus could have a switch to not display these deleted
messages.
Or perhaps just pretend like all \Deleted messages are \Read?

Apparently, that's what we've been doing since 2013:
(let* ((unread
(gnus-compress-sequence
(gnus-set-difference
(gnus-set-difference
existing
(gnus-sorted-union
(cdr (assoc '%Seen flags))
(cdr (assoc '%Deleted flags))))
(cdr (assoc '%Flagged flags)))))
(read (gnus-range-difference
(cons start-article high) unread)))
So I think re-handling this (as the patch suggested) should be
unnecessary, so I'm closing this bug report.
If the problem still exists, please respond to this email and we'll
reopen the bug report.
