(fake) unread messages using nnimap.

(fake) unread messages using nnimap.

[Uwe Brauer]

Hello

I wrote about this some time ago but never saw my mail
posted.
Just in case again: I am using Xemacs 21.4.22 Mule,
nognus 0.11 and the nnimap backend for reading my mail.
My mail I receive using offlineimap and running the dovecot
server on my Laptop. That is why I don't use the agent any
more.

However in every session gnus indicates in several nnimap
groups unread message, where in fact there are not. When
visiting the group *no* unread messages are shown and after
leaving that group in fact the indication of the  unread
messages disappears. 

Does anybody know about this problem and what to do?

thanks

It could be any number of things, but one of the common issues with
offlineimap that I have is:

When you add a new message to a group on the "client" side of an IMAP <=> IMAP
sync pair, offlineimap will upload it to the server, delete it from the
client, then add a new copy with an extra header.

Flags are preserved, though, so the message will show an a "new" item, but
already be read when Gnus looks at it.  This would show in any folder where
you added messages with IMAP on the client side.

offlineimap with a mutable client side (eg: Maildir) doesn't show this problem
because it doesn't need to delete and add a message to add the extra header.

But isn't this also a dovecot issue then?

It seems that you use such a configuration. I have set up my
dovecot offlineimap configuration more than a year ago and
don't remember the details. Could I change the setting? Can
you tell me how.

Thanks

Hi Daniel,

FYI : I offlineimap between a local dovecot and a remote gmail and am
pretty sure I dont see this behaviour.

Are you using GNU emacs or Xemacs?

I don't understand, but I doubt it: everything here is doing exactly what it
says on the box, including the IMAP server, Dovecot, offline-imap, and Gnus.

I don't understand what setting you are imagining changing, but I don't think
it exists: Dovecot and offline-imap can't (to the best of my knowledge) be
told to change the IMAP protocol or anything, so you are stuck with this nasty
edge case.

The new NNIMAP rewrite might help, but I don't actually know.
