 Hello,

I am running a small mailing list with about 450 members usinf Mailman 
version 2.0.6. The list is configured to only allow a select group of 
people post to the list without approval.
I have been getting spammed by a couple of servers. It is getting 
onerous deleting the spam which get through.
 I have put in filters ( Hold posts with header value matching a 
specified regexp.) " from: .*@mdusystems.com" and "from: .*@intrehost.com"
Now I am getting messages from hb528.intrehost.com (unknown 
[66.17.227.138]) will a filter    from  .*@ *.intrehost.com" stop these 
messages from gettin to my approval area?

NB : This spammer also changes IP source addresses EG:  <Delivered-To: 
dealer-list at two.pairlist.net
Received: from hb528.intrehost.com (unknown [66.17.227.138])
<Delivered-To: dealer-list at two.pairlist.net
Received: from hb531.intrehost.com (unknown [66.17.227.121])
<Delivered-To: dealer-list at two.pairlist.net
Received: from hb529.intrehost.com (unknown [66.17.227.139])

 Etc.

 How do I stop this pest?

Any suggestions would be appreciated.
 
Regards,
 Joh Posloski
