If you're using Mandraled Hosting's mail server but want to route emails via another provider — such as G Suite, Office 365, or Mailchimp — you may need to add a secondary sending server source to the SPF record.
Solution: Add multiple includes within the TXT record in Manage DNS. Each include is separated by a space.
Mandraled's default SPF record: v=spf1 include:spf.stackmail.com a mx -all
Examples by Provider
- G Suite:
v=spf1 include:_spf.google.com include:spf.stackmail.com a mx -all - Office 365:
v=spf1 include:spf.protection.outlook.com include:spf.stackmail.com a mx -all - Mailchimp:
v=spf1 include:servers.mcsv.net include:spf.stackmail.com a mx -all - SendGrid:
v=spf1 include:sendgrid.net include:spf.stackmail.com a mx -all
