The acronym SPF identifies which mail servers are authorized to send emails for a domain. Once an SPF record is configured, the SPF result will be checked against any outbound email. If it checks out successfully, the sending server is authenticated; if not, the receiving server considers it spam.
In order to specify Pepipost as an authorized email sending source for your domain, you need to add an SPF record for Pepipost.
Creating an SPF Record for Pepipost
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Pepipost will have the following syntax:
yourdomain.com TXT v=spf1 include:pepipost.net -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 Pepipost. If you do have an existing SPF record in your DNS, you need to modify it to include Pepipost, as shown below:
Previous SPF record: v=spf1 mx include:spf.domain.com -all
Modified SPF record: v=spf1 mx include:spf.domain.com include:pepipost.net -all
Wait for 48-72 hours to allow your DNS to process the changes
