I think this bug report might be describing the same situation I've had
since I started using Claws:

http://lists.claws-mail.org/pipermail/users/2012-June/002676.html

I don't know what the reporter meant by "the heading (on gray
background)". What I've found is that the stuff in the actual message
was right, but the stuff in the list is wrong, and pertains to some
ancient email I once got.

As pertains to my situation, by A/B'ing Claws against Thunderbird, I
found out that the defect isn't in my local Dovecot, meaning:

A: Dovecot didn't cause the problem
B: Claws misread my Dovecot, rather than miswriting it.

This stuff tends to happen more and more until I "rebuild folder tree"
on the account. Doing so sometimes, but not always, cures past
mismatches. I can't tell whether it cures them by making the contents
match the list, the list match the contents, or just deletes the email.
This problem is so rare and intermittent that it's hard to pay
attention.

So I ask the OP: You have a message/list mismatch. Are you sure which
is wrong? What do the dates in each say? If the message view is dated
today, and the list is dated 6 months ago, this tells me the message
view is probably the accurate data.
