SPF Record Lookup
Check which servers can send emails from a domain. SPF records stop spammers from faking your email address.
Understanding SPF
SPF tells email servers which IP addresses can send emails from your domain. If an email comes from an unauthorized server, it gets rejected or marked as spam.
SPF record parts explained:
- v=spf1 - Says this is an SPF record
- include: - Allows another service to send for you (like Mailchimp)
- mx - Your mail servers can send emails
- a - Your website server can send emails
- ip4/ip6 - Specific IP addresses that can send
- -all - Block all others (strictest)
- ~all - Mark others as suspicious (recommended)
- +all - Allow everyone (never use this)
