Getting a TON of these in /var/log/messages
Code:
Dec 17 13:32:58 kif sendmail[95760]: OTP unavailable because can't read/write key database /etc/opiekeys: Permission denied
I'm reluctant to change anything like /etc/opiekeys file permissions seeing as I'm not too familiar with sendmail yet, and I have found little in the way of information on what this actually does, or how to fix it.

I was always under the impression that sendmail ran as root, so I'm unclear how 600 permissions on the file in question could be a problem. But, seeing as how there clearly is a permissions issue, how do I find out what account sendmail is running as also?

OK. I did some reading and figured out what opie passwords are, and that they are to be used by people forced to log in from insecure locations. I created a random user, created an opie password, and successfully logged into my system from a remote (insecure) location. However, I still don't have the foggiest clue why sendmail would be pitch errors about this.

Any ideas?
