How to Define SPF with Custom Records for MIAB?

Help with Setup/Upgrade

Continuing the discussion from How to Define DKIM in MIAB:

Proposed Steps to create a SPF resource record:

  1. Create a custom text record, type TXT
  2. Name is your domain, usually @
  3. Data is “v=spf1 include: box.example.com -a”

Sender Policy Framework(SPF) Resource Records (RR):

  • allow a receiving MTA (Message Transfer Agent) to interrogate the Name Server (DNS) of the domain which appears in the email
  • determine if the originating IP of the mail (the source) is authorized to send mail for the sender’s domain

Notes:

  • the MTA’s SPF handler may not support the SPF RR type but will ALWAYS support the TXT RR type
  • so create a TXT record instead of an SPF record

Do you have a question?

SPF is set out of the box.We don’t check the SPF records on receiving email, this is done because some providers don’t set them properly.
