When Exim complains about not enough disk quota, this can mean several things. This list helps to resolve your problem:
- Check if there is enough disk space in the e-mail account.
- Check if there is enough disk space in the DirectAdmin account.
- Recount the quotas.
- Update Exim.
- Fix the user permissions:
cd /usr/local/directadmin/scripts ./set_permissions.sh email
- If this all does not work and you are using Dovecot:
cd /usr/local/directadmin/custombuild ./build todovecot
