Valid SFP Record?

Discussion created by 7764933 on Feb 1, 2016
We do have a sfp record with "include:o1.mailer.samanage.com", beside of other incluses, mx, ips and so on
Unfortunatly, some customers are not getting mails anymore. We are getting this message back:
"Included domain 'o1.mailer.samanage.com' has no applicable sender policy."
What are the correct sfp settings for samanage?
