Incorrect SPF record

Hi

 

Our domain SPF record includes

 

include:_netblocks.mimecast.com include:spf.protection.outlook.com -all

 

however we have got a message back from the recipient that one of mimecasts IP addresses is being blocked because it is not included in our SPF record as below:

 

The mails we are blocking are sent from this server:

Reverse DNS Hostname: mx1.messageprovider.com (verified)

IP Address: 199.200.24.213

 

I thought the following line

include:_netblocks.mimecast.com include:spf.protection.outlook.com -all

would cover all mimecast servers.

 

Please advise if we just add the IP address above to our current SPF record?

 

Thansk
