Sender Policy Framework (SPF) records help reduce the chance of your domain being spoofed in spam messages. It can also increase the deliverability of e-mail to external providers such as Gmail and Outlook.
We maintain an SPF record that is kept up to date with all IP addresses used to transmit e-mail from our network. This ensures that any e-mail sent from our services passes an SPF check. To use this on your domain, you need to add a TXT record in DNS.
Please add the following TXT record to your DNS
v=spf1 include:spf.stackmail.com a mx -all
You can use the same record for all domains that use our mail services, however it should be noted that the above record will tell external providers all of your e-mail should originate from our network. If this isn't the case the record should be updated accordingly.
