Hi Guys,

My custom domain vibrantcommunities.com.au is set up on Outlook.com and working well, I can send and receive from Gmail, Hotmail, etc, but I cannot email any email addresses on my own personal server.  When I try to send an email from *** Email address is removed for privacy *** to *** Email address is removed for privacy *** I get an error saying it was undeliverable - yet sending to *** Email address is removed for privacy *** is fine. This is using the Outlook.com webmail service.

My personal server resides on IP: 182.160.128.26 if that helps... 

Using the Outlook.com webmail, sending an email to *** Email address is removed for privacy *** or *** Email address is removed for privacy ***, I get the following error:

I can receive ok from my server - and I can send to Gmail & Hotmail... I just can't send to it.

Any ideas?

Regards,

Richard
