If you don’t enable Email Security Compliance, we recommend that you set up a Sender
Policy Framework (SPF) record for your email domain. To pass SPF checks, include Salesforce in
that record.
Required Editions
| Available in: Salesforce Classic and Lightning Experience |
| Available in: all editions except Database.com |
-
If you don’t already have one, create an SPF record. There are many online resources
available if you need assistance with setting up your SPF record.
-
Include
_spf.salesforce.com in your SPF record when
sending mail from the Salesforce application.
Example SPF records:
-
v=spf1 mx include:_spf.salesforce.com ~all
-
v=spf1 mx ip4:204.14.234.64/28 ip4:204.14.232.64/28
ip4:182.50.78.64/28 ip4:96.43.144.64/31 ip4:96.43.148.64/31 include:_spf.salesforce.com
~all
