Your SPF record should include all email relay hostnames that will relay mail for your domain. As long as you ensure there's a PTR in place for each sending mail server IP address, and that PTR specifies the hostname of the email relay, then you should be good.

 

If you can provide more details on your current SPF record and how many email relays you have, I can help ensure you are all setup properly.

Thank you for your answer Cory. We actually do not have an SPF record set that contains the mail gateway host-names (2 nodes, each with an IP address on each link). Our current plan is to update the PTR record for the secondary link IPs with the two host-names (they are using temporary filler names as of this moment)
