Today all my clients from Hotmail are don't receive email. I contact my hosting, and they tell me that is a Hotmail issue.
I get this email:
Connected to 65.55.92.152 but sender was rejected.
Remote host said: 550 SC-004 Mail rejected by Windows Live Hotmail for policy reasons. A block has been placed against your IP address because we have received complaints concerning mail coming from that IP address. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, we recommend enrolling in our Junk E-Mail Reporting Program (JMRP), a free program intended to help senders remove unwanted recipients from their e-mail list: http://postmaster.live.com
