dovecot-0.99.10.x or Mozilla label bug?

[Rick Johnson]

Not to reply to myself, but this appears to be a Mozilla bug. The latest 
Thunderbird nightly (win32 - 012804) seems to have fixed the issue. 
Perhaps I should file the bug in Red Hat's Bugzilla under mozilla in 
order to get the "Fix" backported.
