Hi,
We have been unable to send emails since we switched to our new Service Provider (and received a new IP). We setup PTR records for the new IP but we have been receiving the standard
5.7.1 smtp;550 5.7.1 Service unavailable; Client host [xxx.xxx.xxx.xxx] blocked using FBLW15; To request removal from this list please forward this message to delist@messaging.microsoft.com
We have fowarded the messages as requested, along with a 'Please remove our IP request' to the delisting email address, but its not having any effect. We get a standard reply with a ticket number, but thats all. No follow up, no other info.
We have been blocked for 4 days now and its killing our business. How do we get delisted?
Have also spent 3 hours so far on the phone to various people, none of whom were able to help, other than to keep passing the call along.
