Asked by KC

I want to discard or block all mail from the mailman server, except messages that come from xyz.com and abc.com domains. How can I do this?

In order to do it in a spoof proof way, you have to do it in the MTA, because the envelope sender and any headers can be spoofed.

In Mailman itself, you can use Privacy options... -> Spam filters -> header_filter_rules to look at any and all message headers and accept the abc.com and xyz.com domains and discard everything else.

For example, if you wanted to use a From: header you could use a regexp like

 ^from:.*[@.](xyz|abc)\.com([>\s,]|$)

and an action of accept as the first rule and then a second rule with a regexp of say

 ^.

which will match anything, and an action of discard.

Can you help with this problem?
