does not list any messages anymore

alongside the missing notification, my ~/.xsession-errors gets massively spammed now, here is an excerpt:

Hi!

I am also affected by this bug. I have an SMTP only account for sending mail and an Exchange MAPI acoount for receiving mail. All mail received through the MAPI account is copied to the local inbox by a filter rule. If I disable the "copy all" rule then indicator-applet works fine and shows the number of new messages in the MAPI account. But with the rule activated the new mail counter always shows zero and I have the following message in .xsession-errors:

** (evolution:11278): WARNING **: Unable to find account that matches mbox:/home/kerekfyp/.evolution/mail/local#Inbox

It seems that I have found a workaround for this: set up a fake POP3 account for a non-exsistent server (eg. localhost). After this tweak the indicator-applet shows the actual count of new messages for the POP3 account. Hope it helps....

I have just developed a similar problem:

I upgraded to Karmic (from Hardy) two days ago without any problems, and restored Evolution from a backup file. It worked perfectly for two days. Today, as I was reorganising recent mail into sub-folders, my main inbox started displaying "there are no messages in this folder". I can't find a way of accessing any of this mail. The mail that was in my subfolders is unchanged. I can receive new mail into my main Inbox, but I have lost all messages received before today.

I'm using Evolution to download mail from a POP (gmail) account.

I am quite new to Ubuntu, so I don't have any great ideas for a fix.
Let me know if I can help with any more information.

Thanks.

Just adding that IMAP mail is not displayed in the indicator-applet either.
Package mail-notification and mail-notification-evolution does not work either.

darolu, your problem sounds different, and might be related to confusion over what the indicator is currently designed to show (which is not "unread" mail, but more or less mail you haven't noticed yet by looking at your inbox). See bug 441942 and the hints for debugging there.

Now it does not show any indications of how many unread mail items there are, now only the pop up notification.

Envelope icon also used to change green, not any more.

This functionality stopped working for me right after upgrading to Natty. I have a POP3 account. The attached patch fixes the problem for POP3 mailboxes and (unrelatedly) also works around the lack of XDG sound support in notify-osd (if you use this patch and install the sound-theme-freedesktop package, you will get a sound on new mail).

Note that the patch is not meant to be correct or general. Also note that it is just sad (to say the least) to find that two major desktop functionalities (having a sound on new mail and having the new mail indicator work for POP3 mailboxes) are broken after upgrading a major operating system (Ubuntu) to a major release (Natty).

As a sort of relief, having a sound on new mail was already broken in previous Ubuntu release(s?), since notify-osd simply lacks the relevant implementation.

Ok, could you please explain how to add this patch to Evolution?
When I tried to apply it via

patch -p0 < evolution-indicator-0.2.14-fix-notify-and-sound.diff

I received the following two errors:

patching file src/evolution-indicator.c
Hunk #1 FAILED at 254.
Hunk #2 FAILED at 319.
2 out of 2 hunks FAILED -- saving rejects to file src/evolution-indicator.c.rej

The patch is meant to be applied to the Ubuntu source package:

  apt-get source evolution-indicator
  cd evolution-indicator-0.2.14
  patch -p0 < /path/to/evolution-indicator-0.2.14-fix-notify-and-sound.diff

Then build the package:

  sudo apt-get build-dep evolution-indicator
  dpkg-buildpackage -rfakeroot

And install it:

  sudo dpkg -i ../evolution-indicator_0.2.14-0ubuntu4_amd64.deb

Thanks a lot for your kind explanation. Now the notification works properly. Great job, Sir!

Sadly this patch only works for the main inbox folder. Subfolders are not affected by it and still do not display a blue envelope or how many mails are received in subfolders.

Status changed to 'Confirmed' because the bug affects multiple users.
