Exim mailbox permissions problem

To fix mailbox permissions issues, run the script /scripts/mailperm
on the server, and then check the permissions on the problem mailbox. The permissions should be set to 660.
Begin the forced delivery of the messages in the Exim queue: /usr/bin/exim -qf.
Send a test message to the email address indicated:
mail theaddress@domain.com. -v
Subject: test
.
and watch for delivery.
Finally, view the log at /var/log/exim_mainlog to verify that it was delivered:
tail -20 /var/log/exim_mainlog
