Sender Policy Framework (SPF)
SPF is a Simple Mail Transfer Protocol (SMTP) validation system that verifies the sender's IP address. It lets administrators determine which servers can send email messages from a particular domain. You don’t need to align SPF with your DMARC policy when you send emails from NetSuite. Only set up an SPF record if a recipient’s email system specifically asks for it.
An SPF record is a TXT record using the SPF format with your DNS provider. An SMTP server on the receiving end determines (based on the content of the DNS TXT record) whether the IP address the email message is sent from is approved for that domain.
Email or fax infrastructure or services may require that you to set up a DNS TXT record for SPF.
-
Email Infrastructure and Services: A DNS TXT record for SPF may be required by the email infrastructure or services (as presented by email domains) that you send email to. If you must include a reference to NetSuite SPF, ensure that the definition
include:sent-via.netsuite.comis a part of your SPF record. -
Fax Infrastructure and Services: A DNS TXT record for SPF may also be required by the fax infrastructure or services that you use to send faxes. For example, eFax validates SPF records. If you are registered with eFax to send faxes from NetSuite, ensure that the definition
include:mailsenders.netsuite.comis a part of your SPF record.
Don't attempt to manage access to NetSuite by adding a list of NetSuite IP addresses to an access control list. Rather than using a list of allowed IP addresses, there are better, more secure, and less fragile methods to protect your account from unauthorized access.
