Better prevent from possible spam attack

[neteler]

Hi SAC,

since I monitor all subscriptions to the GRASS mailing lists, I noticed bulk subscriptions to various of our lists at the same time, all from the same domain with likely random user names.

Looking on the list server, this currently accumulates to:

find_member apotmail.com  | grep found | wc -l
259

Apparently we are not alone:  http://www.mentby.com/Group/svlug/probablehaus-domain-apotmailcom.html

I would suggest to bulk-unsubscribe them as mailman admin and block that domain to avoid a mess in the future in many OSGeo lists.

I have solved it for the GRASS lists.
