SPF Record Check for fourseasons.com

The SPF record for fourseasons.com defines exactly which IP addresses and mail services are permitted to send email using @fourseasons.com addresses. When a receiving mail server gets an email claiming to be from fourseasons.com, it checks this SPF record to verify that the sending server is authorized.

If fourseasons.com's SPF record is configured correctly, it protects against email spoofing, preventing unauthorized parties from sending emails that appear to come from fourseasons.com. A missing or misconfigured SPF record can lead to delivery problems and makes the domain vulnerable to phishing attacks.

This SPF record checker breaks down each component of fourseasons.com's SPF record, showing which IP ranges and services are included and whether the policy ends with a hard fail (-all), soft fail (~all), or neutral (?all) for unauthorized senders.

What Is SPF?

SPF (Sender Policy Framework), defined in RFC 7208, works by publishing a DNS TXT record that lists the IP addresses and domains allowed to send email for fourseasons.com. Receiving mail servers check this record to verify that incoming email actually comes from an authorized source.

Without SPF, anyone on the internet can forge the "From" address in an email to impersonate fourseasons.com. SPF helps prevent this by giving receiving servers a way to verify that the sending server's IP address is authorized by fourseasons.com's domain administrators.

SPF Syntax Explained

An SPF record starts with "v=spf1" and contains one or more mechanisms: "ip4:" and "ip6:" specify allowed IP ranges, "include:" references another domain's SPF record, "a" allows the domain's own A record IPs, "mx" allows IPs from MX records, and "all" is the catch-all at the end.

Qualifiers modify how each mechanism is evaluated: "+" means pass (default if omitted), "-" means hard fail, "~" means soft fail, and "?" means neutral. A record ending in "-all" strictly rejects unauthorized senders, while "~all" marks them as suspicious but doesn't outright reject them. Best practice for fourseasons.com is to use "-all" once all legitimate sending sources are accounted for.

SPF Best Practices

Keep the SPF record under the 10 DNS lookup limit. Each "include:", "a", "mx", and "redirect" mechanism counts toward this limit. Exceeding it causes a "permerror" that can result in all email from fourseasons.com failing SPF checks.

Use "-all" instead of "~all" once you're confident all legitimate senders for fourseasons.com are included. Regularly audit the "include:" entries to remove services fourseasons.com no longer uses. If the record is approaching the 10-lookup limit, consider "flattening" includes into explicit IP ranges.

Monitor SPF alignment with DMARC reports. DMARC aggregate reports will show you if legitimate email from fourseasons.com is failing SPF checks, which helps identify missing authorized senders.
