Topic: SMTP Outbound Relay - SPF record
I've got an SPF record setup:v=spf1 mx a include:wiredblade.com include:dynu.com ip4:168.235.105.136 ~allI just add the one IP address today. This SFP generates the too many domain lookups. I'm wondering if you have a list of IP addresses that you send email from so I can eliminate the too many DNS lookups error.Any suggestions?

You only need to include relay.dynu.com in the SPF records. relay.dynu.com points to all the IP addresses of the relay server.
