We are using magento on our server. Magento sent transactional emails directly from our server using php mail function, along with this we are using third party webmail service. Means our mx entry pointing to other server.

Suppose our IP is
220.127.116.11, MX server points to:
New suggested SPF entry will
v=spf1 +a +mx +ip4:18.104.22.168 include:_spf.mailserver.com ?all
