[Mailman-Users] SPAM getting through on moderated lists

[Nuno Serra]

Hi,

SPAM email where the from address appears as the list itself is 
bypassing the list rules for posting and is automatically accepted.

Is this a mailman feature? Does it always approve mail coming from 
itself? Should it?

How can I stop it without turning emergency moderation on (not sure if 
this will stop them or not)?


Thanks,

Nuno
