Here is the story. We are running Redhat Enterprise Linux 4, and were
using Dovecot .99.x . At
one point, we chose to switch from mbox to maildir (and still use
Dovecot). After the switchover
our users reported a bug when using Thunderbird:
"A new behavior that I have observed a couple of times is that the new IMAP
server confuses email headers with content. E.g., I have an email from
but when I go to view it, the contents is just a spam body from an
With this specific bug, adjacent spams are also running into other
occurs I'd say once every hundred messages. Other appearances of this
with adjacent messages concatenated.
I'm not sure how to explain this, maybe what happens is that the new IMAP
server confuses requests and delivers the wrong message bodies to the
which get cached.
This could in some circumstances be more than an annoyance, e.g., with
confidential emails inadvertently getting picked up in replies to people
outside the company."
We proceeded to update Dovecot to the latest available version
However, despite that, our users still report the same bug:
"This bug still persists. In particular, I just (after the new version
clicked on an email from Person X, and Thunderbird displayed an email from
Person Y that I had just replied to. Note that the email from Y was not
adjacent to the one from X (at least, in the temporal ordering)."
I have not been able to reproduce the bug myself. Can anyone think of
where we should start debugging?
