Good site for checking SPF records- http://www.kitterman.com/spf/validate.html

I need to update their SPF record to include a range of ips from which a vendor sends e-mail on their behalf. The current record is: v=spf1 include:spf.protection.outlook.com<http://spf.protection.outlook.com> -all My proposed record is: v=spf1 ip4:x.x.x.x/28 include:spf.protection.outlook.com<http://spf.protection.outlook.com> -all Does this look correct? I'd hate to break their ability to have mail delivered. Thank you, RS
