An SPF record can save your domain from spam and phishing by allowing you to keep a record of your authorized sources. CodeTwo highly recommends their customers set up SPF for their respective domains. Here’s how you do it:
Creating SPF record for CodeTwo:
If you have your own domain, you need to add the CodeTwo Email signatures for office365 domain to your SPF record
Here are the steps to setup SPF for CodeTwo :
- Add the SPF record for the Microsoft 365 domain. The SPF record looks as shown below
v=spf1 include:spf.protection.outlook.com -all
- You need to expand your SPF record by including an entry that corresponds to the Azure region you have selected. For Example, if you have selected North Central US region, the SPF record appears as shown below
v=spf1 include:spf.protection.outlook.com include:spf-us.emailsignatures365.com -all
- Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using CodeTwo. If you do have an existing SPF record in your DNS, you need to modify it to include CodeTwo, as shown below:
Previous SPF record: v=spf1 include:spf.domain.com -all
Modified SPF record:v=spf1 include:spf.domain.com include:spf.protection.outlook.com include:spf-us.emailsignatures365.com -all
- Wait for 72 hours to allow your DNS to process the changes
