SPF (Sender Policy Framework) is a protocol used to check the authenticity of sent emails. Using the SPF-record, mail servers can check whether the email originates from an authorised server.

When sending emails from Congressus Manager, the message isn't actually sent from your own email server. Instead, a third party (Amazon SES) sends the email and labels it as being sent by your email address. Because of this, it is important to set up your DNS in a way to authenticate your emails.

Note: You can only edit the SPF-record if you have access to the DNS settings of your domain name. You cannot use SPF for email addresses of which you cannot change the SPF-record yourself, such as @gmail.com, @outlook.com and @hotmail.com.

Setting up a SPF-record

  • Log in to the DNS settings of your domain name

  • Check if there is already a SPF record present. Recognize it by the type 'TXT' and it starting with 'v=spf1'

  • Do you already have a SPF record?

    • Add 'include:amazonses.com' to the record

  • Do you not have a SPF record?

    • Add a new TXT-record with the value 'v=spf1 a mx include:amazonses.com ~all'

Note: You can only add one SPF record per SPF version to your DNS settings. When you add multiple SPF records, you will make your SPF record invalid.

More Options

Aside from SPF-records we also advise you to use DKIM. This article explains how you can add DKIM settings.
