    I've never used the sec=dh option, what's it suppose to do? I usually
    mount mail soft along with the bg option just incase the mailserver
    isn't up for some reason (power hit or something)... You said you
    could read roots mail just fine that way, so I'm wondering if you are
    trying to mount mail over an existing /var/mail like /var/mail/root ?
