Any objections to adding it from anyone? Please go ahead and add it. It looks clear enough to me. btw, I just decimated your article with loads of other info that people might find interesting. All of that came from my head, so if someone can technically proof read it once would be appreciated. - KB ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

Great - thanks. Got that working so I'll update the page :) Security is one reason, better load handling is another. There is a lot less resources required to setup and teardown a unix socket than a network socket.

[CentOS-docs] Short postgrey guide?
Hi Guys, Are you interested in a brief guide on how to set up postgrey (anti-spam greylisting) with postfix? I set it up today and it took me a while to get it working as the config is slightly different from that on many of the googled guides (many are debian/ubuntu based). The darn config file lives in /etc/sysconfig on RH/CentOS rather than /etc/default as mentioned in all the guides I found!
