SPF Records versus A Records

An SPF record is a Sender Policy Framework record. It's used to indicate to mail exchanges which hosts are authorized to send mail for a domain.

SPF works by a DNS record that specifies the servers that are authorized to send emails on behalf of a domain. The record also specifies how recipients are supposed to handle emails that are sent from an external server other than where the web site is hosted and the domain name is resolving to.

When ADVAIA launches your web site we point the domain URL through your registrars DNS to the following "A" records:

  • *
  • @
  • www

Note that some DNS entires may not contain all three of the above records.

DO NOT MAKE THE MISTAKE of having your registrar point the domain name to the Signature IP address for the SPF record. If you do this your web site will go down as it is no longer pointing to our server where your web site is hosted!

When speaking with your registrar you need to be very specific in your verbal instructions to them. Ask them to create an SPF record that contains the IP address that Signature has provided. If they do not understand that instruction ask for another technician to assist you. If they change from ADVAIA's IP address to the Signature IP address your web site will go down. Clarify with the technician that they are not to change any of the "A" records where the domain name (URL) point to. They should only create an SPF record. You can give them the definition stated above if they are unclear or share this Knowledge Base article with them

This is what the record should look like when created by your registrar:

v=spf1 +ip4:

Note that ADVAIA does not support email services nor do we assist in creating SPF records.
