Mails from Technorati not arriving: not obeying their own SPF rules
As I was looking into problems with my mail server I noticed one more thing: I was wondering why I did not receive password recovery emails from Technorati. It seems as if they are not obeying their own SPF rules:
2008-03-25 14:46:23 H=nat-365m.technorati.com (t120.technorati.com) [208.66.64.4] F= rejected RCPT : Not authorized by SPF
Now I am wondering why someone sets up SPF for his mail domain when he is in fact sending emails from other IP addresses as well. Time to update your SPF rules Technorati...
