[Mailman-Users] Question about a configuration parameter in Mailman 2.0.6

[Alain Chappuis]

Hello,

I have a little question about one configuration under
Mailman 2.0.6

I dont see the exact sens in the Privacy Options at the heading:

"Hold posts with header value matching a specified regexp."

Is there anybody help me to teach me the goal of this heading? 

and in second step:

What hear you by regexp?

many thanks in advance.

Alain.
