Apparently, pm.org mail servers are now doing content-based filtering where any domain names mentioned in your mail get compared against a list of "recently registered domains", which is fetched from: http://support-intelligence.com/dob/
And here's the funny: perl.org just got *renewed*, so for now any attempts to write mail to your perl mongers group wherein you mention something.perl.org will bounce.
Sigh... attempts to fight spam always turn into some absurd exercise. Such as applying multiple layers of adhesive bandages to your very hairy back while you bleed-out through your wrists due to the fact that you've cut off your hands to keep your feet from sweating.
As the domain for yapc-surveys.org was only registered last week, all mails advertising it to the traditional Perl lists got blocked.
So you're guilty of being a spammer, even though no abuse mails have been filed, just because you register a new domain! The irony of their domain name, "support-intelligence", says it all.
That's frustrating, but I think Ask and Robert do a great job of managing pm.org mail.
I look after a list on there and very little spam gets through. I also post to various pm.org/perl.org lists and whenever I've encountered problems one of the system managers has resolved it quickly or suggested a workaround.
Spam filtering is hard, and I generally find pm.org strikes a good balance.
