Okay.

What I did was 

0. Stop all cyrus related processes
1. Sync the mailbox, ommitting cyrus.cache and cyrus.squat only
2. Translate the cyrus.header file to update the ACLs both with the new
   user at domain and the new ACL value using two reg expressions:
	"s/([a-z0-9.-]*)(\s*)(lrs[wipkxtecda]*)/\2@$DOMAIN\3\4/ig"
	"s/lrswipcda/lrswipkxtecda/"
3. Copy the .seen and .sub files from their old location to their new.
4. Make sure permissions and ownerships are correct in the new locations.
5. Run a reconstruct on the mailbox.

I can't say this will work for every situation, but it worked for ours.

I wonder is this due to the loss of cyrus.index and/or cyrus.header.
