I'm sure some have stumbled upon this error and googling it renders little help. It's been a couple of years since it happened to me but today the problem occurred. I (accidentatly) ran yum --disableexcludes=repoid --obsoletes update --skip-broken This updated dovecot or exim and that is a no-no on cpanel servers. Running /usr/local/cpanel/scripts/check_cpanel_rpms sorted out the rpms. However, the problem persited. So the fix: run /scripts/fixquotas (always good to run at times) then run /scripts/reset_mail_quotas_to_sane_values --force- --confirm Finally run 'Repair Mailbox Permissions" from WHM (Solved!)
