[Mailman-Users] newsletter

[Curt Siffert]

Is there a way to keep the email address of a sender from showing up 
anywhere in the headers of the resulting email?

I've got a newsletter with everyone moderated except for one user, who 
I'd like to be able to post to the list.  But if his email address 
shows up in the email, someone else could forge it and be able to spam 
the list, couldn't they?  Unless there's a way to hide the sender's 
email address.  Is there a better way to handle this without requiring 
someone to approve a message through the web interface?

Thanks,
Curt
