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 Authorize SPF authentication on Plesk

• Sign in to your DNS registrar’s account 
• Go to Tools & Settings > DNS Template
• You must change the DNS TXT record for SPF.
• The following syntax is what an SPF TXT record for Plesk will look like:

yourdomain.com TXT v=spf1 +a +mx +a:test.plesk.com -all

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

Worth noting: To enable SPF for outgoing emails using Plesk, simply publish the aforementioned record if your domain has never had an SPF record. If an SPF record already exists in your DNS, it must be changed to include Plesk.

• Save adjustments
• Allow your DNS to process the adjustments for 24-48 hours.
