Following well-known sites (fortune 100 blah blah blah) have already adopted SPF. Not convinced, yet? http://spftools.infinitepenguins.net/earlyadopters.php Just do a "dig txt" and see for yourself. Here's an example of how GMX publishes their records (basically this is what I was suggesting to do): ;; ANSWER SECTION: gmx.net. 289 IN TXT "v=spf1 ip4:213.165.64.0/23 ?all" And here are some stats: http://spftools.infinitepenguins.net/register.php Don't forget to register your domains there after adding SPF records. ".ch" is on place 9 right now (I got it from rank 10 to rank 9, but manually adding domains is quite a tedious task). As soon as they provide me with a bulk add, we'll get it to rank #1! -- Kind Regards Daniel Lorch Full-time SPF evangelist Hostpoint GmbH � � � �| The Data Residence � �| Z�rcherstrasse 2 � � �| 8640 Rapperswil � � � | Schweiz Tel �+41 55 220 0404 �| Fax �+41 55 220 0409 �| www.hostpoint.ch _______________________________________________ swinog mailing list [EMAIL PROTECTED] http://lists.init7.net/cgi-bin/mailman/listinfo/swinog
