o365 Quarantine Blocking Emails from this network

Hey MS and Community Admins - is it worth noting that the emails that spin out of this network are being blocked by o365 Quarantine? We can release and try to retrain for our tenant, but wondering if...

    Emails should not be blocked any longer, this should now be resolved. Thank you so much for your patience.

Hi,

 

I still get these in the Junk folder, because we monitor the SPF conditions for incoming emails. Header shows:

 

Authentication-Results: spf=fail (sender IP is 208.74.204.5)
smtp.mailfrom=o365network.onmicrosoft.com

 

Received-SPF: Fail (protection.outlook.com: domain of
o365network.onmicrosoft.com does not designate 208.74.204.5 as permitted
sender) receiver=protection.outlook.com; client-ip=208.74.204.5;
helo=smtp.lithium.com;
Received: from smtp.lithium.com (208.74.204.5)

 

Perhaps a call to the DNS team is in order.

 

BR,
