Problem with HELO & DNS MX settings

[sebastian at debianfan.de]

Hi,

i am using policyd-weight for fighting against spam on a debian mailserver.

Some companys are using the mailservers from 
outbound.protection.outlook.com - and policyd-weight said (correctly) 
"correct HELO & DNS MX settings".

I want to whitelist all the Mails from outbound.protection.outlook.com - 
there is no other way.

Is there any possibility for whitelisting this host?

thx
Sebastian
