You should always reference these records by their DNS name rather than IP address.

Be sure to use the actual IP addresses in your firewall, rather than hostnames.

SPF Record

If you use an SPF record for your domain, it should be updated to include the following: 
It is recommended that outbound email only be enabled after the Time to Live (TTL) for the SPF record has passed. The use of -all in your SPF record could mean that the remote domain will reject your email if the TTL has not expired.
