Sadly no.

I have a UW-Imap server that stores its mailboxes in MBX format and I
want to copy the content and structure of a huge user (me) into three
other IMAP servers and then do some comparisons. Since each of these
IMAP servers stores their data in (respectively) MySQL, Postgres and
Berkeley DB files it is a bit impractical to write a specific import
routine for from MBX to each sort.

This especially when there is the handy, er..., standard called IMAPv4
which is supposed to insulate us from the implementation details.

So imapsync is actually, for me, just the job - except it does not seem
to work very well nor reliably.
