allure.com SPF Record Checker

Use this SPF record checker to analyze the email authentication setup for allure.com. SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of allure.com.

SPF Record Check for allure.com

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

If allure.com's SPF record is configured correctly, it protects against email spoofing — preventing unauthorized parties from sending emails that appear to come from allure.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 allure.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 allure.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 allure.com. SPF helps prevent this by giving receiving servers a way to verify that the sending server's IP address is authorized by allure.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 allure.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 allure.com failing SPF checks.

Use "-all" instead of "~all" once you're confident all legitimate senders for allure.com are included. Regularly audit the "include:" entries to remove services allure.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 allure.com is failing SPF checks, which helps identify missing authorized senders.

Frequently Asked Questions

Does allure.com have SPF? — The SPF analysis for allure.com shows whether the domain has a published SPF record and details its contents. If no SPF record is found, allure.com has not configured email sender authorization.

What is allure.com's SPF policy? — The SPF policy is determined by the final mechanism in the record. "-all" means hard fail (reject unauthorized senders), "~all" means soft fail (flag but don't reject), and "?all" means neutral (no policy).

Is allure.com protected from email spoofing? — SPF alone provides partial protection. Full email spoofing protection for allure.com requires SPF combined with DKIM and a DMARC policy set to "quarantine" or "reject". Check allure.com's DMARC page for the full picture.

Why is email from allure.com going to spam? — If SPF checks are failing, email from allure.com may be flagged as suspicious. Verify that all sending servers and services are included in the SPF record.
