Hello, I was hoping someone from Microsoft could contact me offlist for
help getting our server (66.151.17.22) removed from the Microsoft
blacklist. I'm having problems sending to outlook.com/msn.com and
others with domains hosted at office365. I can't find any issues with
the server, and I don't appear to be on any other blacklists, but all
messages to Microsoft are either getting rejected or sent to the spam
folder. The mailserver has been at this IP for many many years, but
these issues just started about 10 days ago.
Any help would be appreciated.
Error message;
<<< 550 5.7.1 Unfortunately, messages from [66.151.17.22] weren't sent.
Please contact your Internet service provider since part of their
network is on our block list (S3150). You can also refer your provider
to http://mail.live.com/mail/troubleshooting.aspx#errors.
[BN8NAM12FT057.eop-nam12.prod.protection.outlook.com]
The link does not appear to have any way for admins to view/remove the
server from the blacklist.
Thank you,
