SPF records are used to help prevent email spoofing. They help to ensure that only authorized servers can send emails on behalf of your domain. SPF records can help to improve your email deliverability.

How to Configure SPF for CodeTwo

The steps to configure SPF for CodeTwo are as follows:

• The Microsoft 365 domain’s SPF record should be included. This is how the SPF record appears:

v=spf1 include:spf.protection.outlook.com

• You must add an entry to your SPF record that is specific to the Azure area you have chosen in order to expand it. For instance, the SPF record displays as follows if the North Central US area was chosen.

v=spf1 include:spf.protection.outlook.com include:spf-us.emailsignatures365.com -all

• This record should be published in the DNS records section for the relevant domain.

Worth noting: To activate SPF for outgoing emails using CodeTwo if your domain previously lacked an SPF record, all you need to do is publish the aforementioned record. If your DNS already contains an SPF record, you must update it to include CodeTwo as shown below:

Previous SPF record:  v=spf1 include:spf.zoho.com -all

Modified SPF record:  v=spf1 include:spf.zoho.com include:spf.protection.outlook.com include:spf-us.emailsignatures365.com -all

• Save adjustments.
• Allow your DNS to process the adjustments for 72 hours.
