Enable Email Security Compliance
Email Security Compliance updates the envelope from address in emails sent from
Salesforce. With this feature enabled, the email header from address is your email address, but
the envelope from address is *.bnc.salesforce.com.
Salesforce’s Sender Policy Framework (SPF) record authorizes the IPs used by our message transfer
agents (MTAs) to send email from our domain. Email sent from Salesforce passes SPF checks even if
you don’t have an SPF record for your email domain.
