I used this to migrate from uw-imapd to dbmail:
imapsync \
--host1 "$src" --user1 "$user" --password1 "$newpw" \
--host2 "$dst" --user2 "$user" --password2 "$newpw" \
--skipheader
'(^X-|^Received|^MIME-|^Content-Type|^Disposition-|^From|^Cc|^Reply-|^Subject|^To|^DomainKey-).*'
\
--skipsize --syncinternaldates \
--exclude '^\..*' \
--include 'mail/.*' \
--fast \
--nosyncacls

That's a feature added because of popular request.

Those are both gmime issues. GMime has it's own ideas about quoting mime
parameters, and wrapping of long lines.
Using a correct skipheaders setup will allow you to sync reliably, at
least that's my experience.
