Bugzilla Bug 143

I have been finding this slightly annoying recently and would love it to be 
sorted if possible.

When a new e-mail comes in it is highlighted in the folder list by making the 
folder name bold and showing the number of new e-mails in the folder - Great!  
If new mail is in a sub-folder that is then collapsed, the parent folder shows 
the bold and dots in brackets - also great!

However, if the new mail arrives to an already collapsed sub-folder no new mail 
alert is shown on the folder list.  Similarly, if new mail is shown in an IMAP 
no notification is shown - not even the blinking icon on the taskbar for this 
one!

To enhance IMAP and correct the POP function of highlighting folders with new 
mail would be great - I can't leave all folders open all the time, but would 
love to know when new mail arrives!

This is an amazing program though, I must congratulate you again!
