[Mailman-Users] spam protection

[Falko Richter]

Hello everyone,

I´m using the mailman from my university for a big project (12 mailings 
lists) there is some amount of spam and i would like to filter a little 
bit. I only want to accept mails from my university ( ***@fhtw-berlin.de 
) and from the domain of the project ( ***@dpwk.de ).

Is there an option to do just that? some sort of regex-filter for 
incoming mail?

Thanks for the support

Falko
