At our business we are running a server for sending newsletters. Setting up the server and sending bulk e-mails is not the issue. That's all working fine.
I run a test on www.mail-tester.com to see how good the mail will pass spam filters. But unfortunately, we are running stuck on the SPF records.
Our setup:
- ISP: Business fiber connection with fixed IP. The ISP has setup our hostname as "mail.ourbusiness.com" (fictional domain name)
- Website: Our website www.ourbusiness.com is hosted in a datacenter and has nothing to do with our ISP.
The following errors occur:
- You're not fully authenticated
- We found an SPF entry on your server but it has still not been propagated
- Your message is not signed with DKIM
See list of the complete fault message.
It say's that our business IP is successfully associated with mail.ourbusiness.com (so that's good).
Now my question: What should our SPF record be? I can find enough information about SPF records, but I have totally no clue of what I need to put into it!
