[Mailman-Users] removing post from mail archive

[Schwartz, Robert]

Is there a way to remove some test posts from the mail archive.  I have found a message:
3.3. How can I remove a post from the list archive / remove an entire archive?
 But I do not have access to the server.  Can I do it from another system from the cmd prompt by using something like:

Mailman-subscribers.py -c -o output-members.csv (link to webpage) (list)
Which I use to export my mailing list.  Where link to webpage is the URL to my website and list is the name of the member list that I want.
