I need to enable to services (Outlook.com and Zendesk.com) to send email on our behalf. The individual SPF records for each would be the following:
v=spf1 include:spf.protection.outlook.com -all
v=spf1 include:mail.zendesk.com ?all
My understanding is that there can only be one SPF record. So what would be the correct record that combines both of these servers?
