[Mailman-Users] How to stop spam emails

[Vinita Aggarwal]

Hi

I am not very sound in mailman configuration.

I have a list in which anyone can post. "Hold the positing from non
members".

Now, I am getting everyday about 100s of spam emails in that list. Please
advise how to deal with this?


Regards,
Vinita Aggarwal

yes

which is our case, because of the call to 'arch'
