Set up SPF for MailNesto

SPF authorizes MailNesto to send on your domain’s behalf.

Step-by-step

1. In your DNS provider, edit the existing SPF TXT record for your root domain (e.g., example.com).
2. If one exists, append: include:mailnesto.com before the ~all or -all mechanism.
3. If no SPF exists, create:

v=spf1 include:mailnesto.com ~all

Only one SPF TXT record is allowed per domain. Combine mechanisms into a single record.
