Rep actually mentions the program they use. Hello Bob, My name is Anja from Windows Live Hotmail Domain Support. I understand that you have changed the servers you are sending your mail from and now messages are being delivered to the Junk Mail Folder in Hotmail accounts. I have investigated the IPs that you have mentioned and only see connections from the IPs 72.35.68.58 and 72.35.68.61. For today, we do see filtering only on the IP 72.35.68.61. ( I only tested from a few virtualhosts on hotmail, some got through no problem.) Hotmail bases its spam rating on the content of a message and the reputation of the sending IP address. When an IP is new, it will not have built a reputation yet. Therefore, it may happen that it is filtered more severely than a well used IP with a good reputation. However, if you keep following the industry best practices a good reputation will be built quickly and filtering will stop. (reputation....takes time) We may be able to help you over the beginning issues that you are experiencing, however, before we can do that we would like you to publish SPF records for each of your sending domains. This technology allows SmartScreen to better track emails from your IP, weeding out spoofed messages. In turn, this will help to improve the reputation of your IP address. You can find additional information on creating SPF records at http://www.microsoft.com/senderid. We have also published a document on email delivery at http://www.microsoft.com/postmaster. (microsoft uses a different standard thqn regular spf, spf/pra or something like that. Where yahoo wants domain keys, google wants regular spf...again, all about time for new ip addresses, even if you have these things) Once you have published SPF records for all your sending domains, please contact us again and we will further investigate the issue. Best regards, Anja Windows Live Hotmail Domain Support
