Exim: Not enough disk quota

When Exim complains about not enough disk quota, this can mean several things. This list helps to resolve your problem:

1. Check if there is enough disk space in the e-mail account.
2. Check if there is enough disk space in the DirectAdmin account.
3. Recount the quotas.
4. Update Exim.
5. Fix the user permissions:
   

   cd /usr/local/directadmin/scripts
   ./set_permissions.sh email

6. If this all does not work and you are using Dovecot:

cd /usr/local/directadmin/custombuild
./build todovecot
