What is SPF?

Sender Policy Framework (SPF) is an email authentication protocol that allows a domain owner to specify which email servers he will use to send email from this domain.

Why configure SPF?

An SPF-protected domain is less attractive to phishers and is, therefore, less likely to be blacklisted by SPAM filters, ensuring the delivery of legitimate email from that domain.

As it is for DKIM, for now, configuring SPF is an additional element that reduces the risk of your email being classified as SPAM. 

However, it is likely to soon become a standard requirement.

The best action to be taken, then, is to proactively configure SPF even before it is required; thus reducing the risk of your email not being delivered.

How to configure SPF?

First, you need to access your account on your server. So, to properly configure SPF for your domain, you must add the following DNS record:

Type: TXT
Name: include: _spf.edrone.me.
TTL: 14400


a) If your domain already has an SPF record, you don't need to add an extra TXT record. The existing TXT entry can contain several separate indications with spaces. It is only necessary to modify the existing entry by adding before the symbol "~ all" the entry “include: _spf.edrone.me.”; 

b) If your domain already has an SPF record for edrone as "include: _spf.emaillabs.net.pl", please, replace it with “include: _spf.edrone.me.”.

How to check if your domain SPF is configured correctly?

  1. Use this online tool

  2. In "Domain" enter your domain (without www or http: //)

  3. Click on "Validate SPF"
