[AusNOG] Microsoft outlook.com, live.com, Office365 etc IP blocking

I've had the exact same issue.  It doesn't work, well, I've applied and begged and did everything I can. I'm still being blocked.

I've had to ship my emails to SendGrid as my SMTP relay. 

I've gone on postmaster live, I've signed up my IPs (with the help of Servers Australia) and white listed it. 

Joining SNDS and JMRP is what you are suppose to do... doesn't seem to do anything though. 

I've written to Microsoft, got a response from someone. No effect.

I've called them up, which was a waste of time, they told me I had to do it online.



Regards,

Hey Paul,

Have you registered with https://postmaster.live.com/snds/index.aspx ?

Once registered you can request access to all IP's with a source of your ASN and see whats going on from MS's perspective.

Cheers,

Bill
