I can not re-iterate enough that this is an unsupported way of
"syncing" your mail across multiple machines.  You are lucky it hasn't
broken before; it will break again.  The devs do not (and should not)
consider the consequences of changes they make in such a scenario.
Ultimately you are going to loose all your data.

If you need to use mail across multiple machines, then use a supported
method such as keeping your mail on a server and using IMAP.
