Description
The Exclaimer service uses a number of Simple Mail Transfer Protocol (SMTP) hosts which help in moving your email across networks to complete the simple actions of sending and receiving mail, between the email sender and receiver.
For your domain, if you add additional include mechanisms to the Sender Policy Framework (SPF) recordsand this causes them to exceed the 10 Domain Name System (DNS) lookup limit - you can add the IP address (specific to the region where your Exclaimer subscription is hosted) to the SPF records.
