Post SMTP Outbound Relay - SPF record

I've got an SPF record setup:

v=spf1 mx a ip4: ~all

I 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 in the SPF records. points to all the IP addresses of the relay server.
