All of our mail is routed through a premium delivery service called ‘MailChannels’. As such, the SPF records need to indicate this to ensure accurate delivery.
Correct Sender Policy Framework (SPF) records need to be configured in your DNS settings to ensure that Internet receivers will properly identify and receive your email. This article describes the DNS records you must add.
The following records are needed for SPF to work correctly. Replace example.com with your own domain name:
example.com 14400 IN TXT v=spf1 a mx include:relay.mailchannels.net -all
If you already have an SPF record, simply add include:relay.mailchannels.net to this entry. Make sure to add it BEFORE the “all” mechanism as “all” always matches and typically goes at the end of the SPF record.
