By default, emails sent from FF will be sent by email@example.com. You can customise this email address to an address you own and manage, and that, more importantly, matches your custom domain. This will ensure that you adhere to email protocols and email sent by FULL FABRIC is not marked as spam.
Sender Policy Framework (SPF)
Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorized by that domain's administrators.
Set up SPF using IPv4
You can choose to give permission to a specific IP address to send mail for your domain. This is accomplished using the ip4 mechanism.
Only mail coming from that particular IP address will be considered a permitted sender for that domain. An example of such an include looks like this:
v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com ip4:220.127.116.11 ~all
FULL FABRIC's IP address is 18.104.22.168
Set up SPF using hostname lookup
If you have an SPF record set for your root domain (i.e. yourdomain.com), you must add
before the 'all' mechanism of this record. If you do not have an SPF record for your domain you must create a TXT record with the value:
v=spf1 include:sendgrid.net ~all
Do not create more than one SPF1 record for a given domain. If you need more than one SPF record, you will want to merge the additional SPF records into a single SPF record.
