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 '
Do you already have a SPF record?
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.
Aside from SPF-records we also advise you to use DKIM. This article explains how you can add DKIM settings.
