Hi

I am getting the following error when I try to send an email from the queue in WHM.

LOG: MAIN
cwd=/usr/local/cpanel/whostmgr/docroot 6 args: exim -C /etc/exim_outgoing.conf -v -M 1HbaHE-0002Qf-LS
LOG: PANIC DIE
Exim configuration error for virtual_userdelivery_spam transport:
quota_directory must not be set without "directory"

any thoughts?

Thanks
Brendan
