If someone could help me with this it would be greatly appreciated.
 
I know how to accomplish what was done but don't know how to prevent
it from happening.
 
Someone has taken it upon themselves to make a personal attack on one
of my subscribers. This morning he/she evidently changed the setting
for my subscriber to NOMAIL. My subscriber was notified of the changes
as the perpetrator was not knowledgeable enough to use the QUIET
variable.
 
What is the best method to keep this from happening again? Can the
list be restricted to changes by the owners only and by using the
validate option resolve this problem?
 
Now on to the second situation.
 
The list is private and you must be a subscriber to post. Someone has
gotten around this using the same method above. He is using the same
subscriber's address to bypass the restriction. I can't say it was the
same person but I'm fairly sure it was.
 
Now I know there are several web bulletin boards that would allow this
to be accomplished. Is there any methods I can use to prevent
unauthorized posting to the list? This is of course discounting, for
the moment, of setting the list to REVIEW. I'm still shying away from
that option.
 
Here is the header from the unauthorized post. While originating from
Germany it appears to come from my subscriber.

---End Forward---
 
I have spoken with the subscriber and he has no knowledge of the
post. In fact, the perpetrator tried to send it numerous times and the
subscriber was aware only due to bounced mail.
 
Again, can someone help me here. As I'm set to digest a personal
reply would be appreciated.
 
Thanks,
