As I read my new mail messages, the icon does not disappear from the system tray, long after the messages have been marked as read. Reproducible: Sometimes Steps to Reproduce: 1. Open MailNews 2. Switch to another window (like Browser) 3. Receive e-mail 4. Switch to MailNews and read new e-mail 5. Look at taskbar Actual Results: the new mail icon didn't disappear Expected Results: It should disappear when the first new message was being read One time while I was clicking on the icon, the icon did go away somehow, but it never showed again when the notification came up for new mail. The only way to fix it was to close all Mozilla windows and restart.

I have seen this happen as well. It doesn't seem to go away until I check for new messages. The other thing that bugs me about the new mail icon behavior is that if you have filters that delete email, and all the email that just arrived new is deleted, you still get the new mail icon! It won't be cleared until you check for new mail. I am using IMAP, so my guess is the code is not taking into account that I have deleted this emails, since technically they are still in my inbox until I "compact folders." The new mail icon should only remain in the task bar as long as there are unread messages in any folders EXCEPT the Junk/Trash folders, and so long as those new messages are not marked in IMAP for deletion.

Frank S, are you also using IMAP? Regarding deleted mails: even with POP mail, using a filter that deletes the message will cause a notification (bug 91498). There are many bugs relating to the use of the Mark As Deleted model of IMAP. The new mail icon in the taskbar (and also, the green-arrow on the Mail icon in the Mozilla Component Bar, bottom left of each Mozilla window) is supposed to clear as soon as any indication is made by the user that new mail has been acknowledged -- not just reading the new mail, but even just switching to a folder in an account that has new mail. I have not seen a case with my POP3 accounts where that icon does not clear as soon as I do practically anything.

I'm just using a simple POP account, with only a couple filters to move messages, and no delete filters.

The new mail icon does clear if I click on the inbox folder, but the problem is I get a lot of email that is deleted by filters (currently, a bug in our mail system is generating email and I don't have time to fix it, but other things like that come up). What happens is you then have to look at the mail program, because it claims there is new mail present, when actually it has been deleted.

If you use filters to move/delete mails, then I think it is a dupe of Bug 222068.

Yeah. After reading that bug more carefully and doing some tests, it is actually a dupe of bug 222068. Sorry about that. *** This bug has been marked as a duplicate of 222068 ***
