SPF Records versus A Records

1/14/2020 12:05:21 PM

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 entries 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 COULD look like when created by your registrar, but this really should be completed by them not you:

Instructions from Signature

SPF Record Update

In a continuing effort to improve overall deliverability of Signature campaigns and member generated campaigns using the Signature system, we are strongly urging all of our participating members to work with their IT administrator/web host to update their Sender Policy Framework (SPF) record to include Signature's sending Internet Protocol (IP) immediately.

VERY IMPORTANT: We recommend that you forward this information to your IT administrator, your Web Host or your Internet Service Provider (ISP) to properly update your SPF. Please do not attempt to update this yourself if you are not familiar with the procedure. An incorrect entry in the SPF could adversely affect your overall email deliverability.

It is important to update your SPF because email domain owners must publish or declare all of the IP addresses used by their outbound email servers or list the IP's that are authorized to send email on their behalf in the Domain Name System (DNS). All of the valid IP's that are able to send email for the domain should be included in your SPF text file.

Below is the Signature IP address that should be added to your SPF:

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