Note that the patch you sent didn't reach any list you probably sent it to (netfilter-devel, netdev, lkml). I'm seeing it just because Florian answered. This is probably the same issue we had with your openvswitch patch last year. By the way, the IP address you used last time is now reported as being "blocked" by: zen.spamhaus.org pbl.spamhaus.org I guess vger might filter using Spamhaus lists (including their "PBL"), which won't let your email through if you're running a mail server with an dynamic IP address. I don't support this practice, but this might be the issue. You can quickly get an overview of blacklists your address might be on at e.g.: http://www.anti-abuse.org/ -- Stefano
