[Dovecot] dsync not copying all mail

[Nick Rosier]

Hi,

I'm still trying to migrate from Dovecot 1.2.16 to 2.0.7 on FreeBSD. 
Previous attempts have failed with mails not being visible after the 
upgrade. Version 1.2.16 was migrated from maildir to dbox about a year 
ago via the convert-plugin. After previous attempts to "clean" the 
hybrid maildir-dbox situation I used imapsync to copy all mails from the 
old account to a new account. I would assume in this case I get a clean 
dbox-mailmap. I tried to run dsync on this new map but noticed a lot of 
mails are not syncing:

[vmail at mail ~]$ find /vmail2/new/bunbun.be/nick | wc -l
     5329
[vmail at mail ~]$ find /vmail2/old/bunbun.be/nick | wc -l
     6134

Any ideas?
N.
