Could you provide some information about the involved folders? Which one is the
MBox? The one which gets the mail from POP at download or the one which is the
filter target?

The crash happens when moving message data in the mbox file due to compacting
it after some message(s) got deleted.

So my guess is that is the folder which the mail got downloaded to orginally
before it gets moved (i.e. the POP3 inbox).

Sure, I just wanted to be sure you know the options.

Depending on your setup, if the POP3 target folder is really the mbox in this
crash, I would actually recommend to make that a maildir.

MBox is by its single file nature very bad for deleting messages. The program
working with the mbox (in this case the resource) needs to remember the
deletion somewhere else and at some point create a new mbox file with all
messages but the delete ones.

In the worst case (first message being deleted) this requires the whole mbox
file to be processed.
