SPF spam protection issue - is the record correct or too long?

bradz

Regular Pleskian
In order to get emails from deluxe.com, I had to totally turn off SPF protection or set it to a higher level and turn on "First, SPF performs a DNS lookup. Select this option to continue checking if the DNS lookup fails...."

The later option caused several other clients to not get emails from clients - too many people with no spf.

Question: Why is the server rejecting this spf or timing out on it?

v=spf1 a mx ip4:168.135.189.30 ip4:168.135.2.206 ip4:65.208.98.0/24 ip4:168.135.189.50 ip4:168.135.190.111 include:mktomail.com include:spf.protection.outlook.com include:_spf.qualtrics.com ~all

Any insight appreciated.
