You can use `mbtool -r` to change the uniqueid of a mailbox, allowing you to
fix this. Obviously this should never happen but maybe you restored mailboxes
with the same "uniqueid" at some point in the past.
Usage:
mbtool [options] {-r|-t} mailbox...
Commands:
-r create new unique IDs for specified mailboxes
-t normalise internaldates in specified mailboxes
Options:
-C alt_config use alternate imapd.conf file
