Outbound mail blocked by hotmail

Our outbound emails to hotmail.com and pretty much any Office 365 accounts is bouncing with this message:

 

   host mx1.hotmail.com [65.55.33.119]: 550 SC-001 (COL004-MC5F26) Unfortunately, messages from 203.45.92.139 weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.

 

The troubleshooting page wasn't much help:

550 SC-001Mail rejected by Outlook.com for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation. If you are not an email/network admin please contact your Email/Internet Service Provider for help.

  • Yes it was, thank you
  • No, I still need help

Re: Outbound mail blocked by hotmail

Hi ObjectiveChris,

 

Can you confirm that all the required DNS entries are in place?

 

Are you able to try send an email from a different network connection? (To confirm that it's not a network issue)

 

If this is still happening, please fill in this contact form, so that we contact you and look at your specific account www.telstra.com/business/tsuitequestion
