Maybe there's some errors with that mailbox which can help us ? On the=20=20
source ? On the dest ?

Did you to try to sync only that mailbox ? Or all mailboxes but this one ?
           -u, --userids
               User mode.  Remaining arguments are list of users who=20=20
should be replicated.

Only some of its folders ?
           -m, --mailboxes
               Mailbox mode.  Remaining arguments are list of=20=20
mailboxes which should be replicated.
