- You want to add the IP address records to your SPF record to allow emails to come from OCLC
Here are the IP addresses you need to allow with your SPF (Sender Policy Framework) record:
- The mailhost IP address - 18.104.22.168 or 22.214.171.124 (mhostap01pwdu.illiad.oclc.org) if OCLC is hosting your address.
- A secondary IP address should be also be added as a failover IP address of the mail server (126.96.36.199 - mhostap02pwdu.illiad.oclc.org).
- The IP address of your Web Server if you are hosting your email.
- Also, allow for Relay.
