I have setup an online service which allows record labels to login, upload their music and then email their music to a list of djs which i guess works on the same principle that a newsletter would do.
The Record Labels are able to enter in their email address so when they hit send to the Djs the mail looks like it has actually came from their domain!
Recently, hotmail has started bouncing these emails back with the following error -
SMTP error from remote server after MAIL command:
550 SC-002 Mail rejected by Windows Live Hotmail for policy reasons.
The mail server IP connecting to Windows Live Hotmail has exhibited namespace mining behavior. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com
for email delivery information and support
Do you have any ideas on how i could get around this issue?
