Savannah Guthrie has taken to social media to announce that her family is willing to pay up to US$1 million (approximately $1.41 million) for information that can lead to the whereabouts of her mom Nancy.

Nancy Guthrie has been missing since February 1.

Guthrie Family Raises Reward

In a video posted on social media, Savannah Guthrie also acknowledged the possibility that her mom may already have passed away.

“We also know that she may be lost, she may already be gone,” she tearfully said in the video. “She may already have gone home to the Lord that she loves and is dancing in Heaven… and if this is what is to be, then we will accept it.”

“But we need to know where she is,” the “Today” host emphasized. “We need her to come home.”

According to PEOPLE, the family also donated US$500,000 to the National Center for Missing and Exploited Children.

A source close to the family also explained to PEOPLE why the family chose to raise the reward. The FBI’s reward of US$100,000 (approximately $141,000) remains active.

“The family first raised this on the first day of the investigation and has been ready to do this ever since,” the source said.

The source added, “They were advised by all involved in the investigation that doing so earlier might overwhelm the infrastructure set up to field leads, tens of thousands of which have been coming in organically.”

Nancy Guthrie Is Still Missing

Since her February 1 disappearance, Nancy Guthrie has yet to be found. She is believed to have been kidnapped by an armed man.

Nancy Guthrie’s surveillance cameras were able to capture the masked man, and the FBI described him as “male, approximately 5’9″ – 5’10” tall, with an average build.”

However, authorities are not ruling out that this masked man may have had an accomplice.

Pima County Sheriff Chris Nanos said that the search for the “Today” show host’s mom could take years.

“Maybe it’s an hour from now,” Nanos said, per The New York Times. “Maybe it’s weeks or months or years from now. But we won’t quit. We’re going to find Nancy. We’re going to find this guy.”

An online SPF checker is a purpose-built diagnostic tool that verifies your Sender Policy Framework configuration in DNS and helps ensure SPF compliance across every domain name you manage.

By running an SPF check or SPF record check, you confirm that your SPF record correctly lists authorized senders, including the IP addresses and subnets used by your outbound mail servers and service providers. Done regularly, an SPF lookup and SPF validation workflow reduces email delivery friction, supports email security goals, and improves overall email deliverability.

A modern SPF checker pairs SPF record lookup with a readable SPF result and clear guidance to correct SPF errors. Many SPF validator interfaces include a DNS lookup to resolve includes, flatten indirect references, and highlight SPF record issues such as too many DNS-mechanism lookups, missing all mechanisms, or ambiguous qualifiers. Because email authentication is cumulative, an SPF checker is most effective when combined with a DMARC record, DKIM record, and policies that address spoofing, phishing prevention, and fraud prevention at the domain level.

Use an SPF validator whenever you add a new sending platform, change authorized IP ranges, or alter routing. Frequent SPF checks help you catch SPF validation errors early, maintain SPF compliance, and protect sender identity before delivery issues arise. Before sending a bulk email campaign, it’s always a smart idea to perform an SPF check online to ensure your domain is properly authenticated and protected against spoofing.

Why SPF Matters: Role in Email Authentication and Brand Protection

SPF is the Sender Policy Framework that lets a domain name publish which hosts are authorized senders of mail for that domain. Receiving MTAs evaluate SPF during email delivery to determine whether the connecting server’s IP addresses (or broader subnets) are permitted. This SPF validation step combats email spoofing, reduces security risk from malicious senders, and contributes to domain security and domain authentication.

• Brand protection and sender reputation: Accurate SPF configuration helps reduce spam sent in your name, strengthens sender reputation, and supports inbox placement. In tandem with DMARC and DKIM, SPF contributes to a layered defense against email-based threats.
• Deliverability and diagnostics: Consistent SPF record check routines uncover SPF errors that can harm email deliverability. When you analyze headers with an email header analyzer, you can see the SPF result aligned with the authenticated domain, aiding prompt resolution of authentication issues.
• Governance and compliance check: Many mailbox providers and industry frameworks expect minimum authentication with SPF, DKIM, and DMARC. Routine SPF check and SPF record lookup cycles serve as a practical compliance and security safeguard.

How SPF Works and How to Interpret Results

MAIL FROM and Return-Path Flow

During SMTP, the sending server declares the envelope sender in the MAIL FROM command (also recorded in the Return-Path). The receiving server performs an SPF lookup on the domain name in MAIL FROM, compares the connecting host’s IP addresses against the SPF record, and returns an SPF result (pass, fail, softfail, neutral, none, temperror, permerror). That SPF result helps determine email delivery disposition and is often visible when you analyze headers for diagnostics.

If MAIL FROM is empty (bounce messages), SPF switches to checking the HELO/EHLO identity. Accurate configuration ensures the correct sender identity is authenticated even for system-generated mail.

DNS TXT Records and Evaluation Order

SPF is published as a DNS TXT record at the domain root or a relevant subdomain. A DNS record checker or DNS lookup reveals the TXT string beginning with “v=spf1”. The evaluation order processes mechanisms from left to right until a match is found. Well-formed records enumerate authorized senders via mechanisms and optionally constrain them to specific subnets. A robust SPF validator traces includes and a records, flags DNS-related SPF errors, and assesses overall SPF compliance.

Evaluation and Lookup Limits

• SPF lookups are limited to 10 mechanisms/modifiers that cause DNS queries (include, a, mx, ptr, exists, redirect). An SPF checker will warn if your SPF validation encounters too many lookups.
• Redundant or contradictory entries are common SPF record issues and may yield SPF validation errors or permerror outcomes.
• Mailbox providers may treat softfail and neutral as increased risk level. Periodic monitoring with a domain scanner and diagnostics can identify such security gaps before they affect email health.

SPF Record Lookup and Interpreting the SPF Result

An SPF record lookup confirms that the SPF record exists and resolves all referenced hosts. A comprehensive SPF check correlates the connecting IP with the authorized IP list and returns a pass when alignment is met. Failed lookups or misconfigured includes often produce SPF errors with delivery issues. To maintain email security and email deliverability:

Use an online tool to run an SPF test whenever you onboard a new sender or change subnets.

Perform diagnostic tests that simulate connections from each authorized IP range.

Capture failures report data via DMARC to prioritize prompt resolution and risk assessment.

SPF Syntax and the Compliance Landscape

SPF Record Syntax Explained

SPF record syntax is built from mechanisms, qualifiers, and modifiers that define which systems can send for your domain name.

Mechanisms, Qualifiers, and Modifiers at a Glance

• Mechanisms: ip4, ip6, a, mx, include, exists, ptr (discouraged), all
• Qualifiers: + (pass, implicit), – (fail), ~ (softfail), ? (neutral)
• Modifiers: redirect=, exp=

A typical record: v=spf1 ip4:203.0.113.0/24 include:_spf.example.net -all

How they work:

• ip4/ip6: Enumerate authorized IP addresses and subnets for explicit allowlisting.
• a/mx: Authorize the A or MX records of the domain or a specified host.
• include: Delegate authorization to another domain’s SPF record (e.g., a SaaS sender).
• all: Catch-all at the end, typically -all for strict SPF compliance or ~all during testing.
• redirect: Point SPF evaluation to another domain name’s record for centralized control.

An SPF checker or SPF raw checker will parse these elements, perform SPF record lookup on includes, and surface SPF validation errors such as unexpected mechanisms, unused modifiers, or broken DNS references.

Examples and Common Pitfalls

v=spf1 ip4:198.51.100.10/32 include:_spf.mailhost.com include:_spf.marketingplatform.com -all

• Avoid exceeding 10 DNS-mechanism lookups; flatten includes if needed.
• Subdomain-specific senders:

v=spf1 a mx ip4:192.0.2.0/27 -all

• Be precise with subnets to prevent unintended authorization.
• Gradual rollout with softfail:

v=spf1 include:_spf.example.net ~all

• Move to -all after monitoring DMARC data and confirming no legitimate sources are blocked.

Helpful tooling:

• SPF record generator to compose correct syntax.
• Record checker and DNS record checker to validate publication.
• Email header analyzer to correlate SPF result with real traffic and inbox placement outcomes.

Compliance Landscape: RFC 7208, Google/Yahoo, and Industry Standards

SPF is standardized by RFC 7208, which defines processing rules, lookup limits, and error handling. Aligning with RFC 7208 ensures interoperable SPF validation and reduces authentication issues across diverse DNS providers and MTAs.

Minimum Authentication for Major Providers

• Google and Yahoo sender requirements emphasize minimum authentication with SPF and DKIM, plus DMARC alignment for bulk senders. Maintain consistent SPF alignment with your visible domain, publish a DMARC record with an appropriate policy, and ensure a passing DKIM record for your streams. Supporting controls like BIMI record, MTA-STS, and TLS-RPT enhance domain security and email protection but do not replace SPF.
• Conduct a compliance check periodically: run an SPF check, a DKIM checker, and a DMARC checker, then verify BIMI where applicable. Use MX Lookup to confirm routing and screen Blacklists to protect domain reputation.

Monitoring, Reporting, and the Tooling Ecosystem

Operational excellence requires continuous monitoring, reputation monitoring, and reporting. Consider a stack that includes:

• MxToolBox SuperTool for DNS lookup, SPF lookup, DMARC, and Diagnostics.
• EasyDMARC for Managed DMARC, Delivery Center, Alert Manager, Email Verification, and an Email Deliverability Test; educational resources such as Academy EasyDMARC help teams master email policies.
• Domain Scanner and Email Health dashboards to scan domain configurations, surface security gaps, and track domain health.
• Email Header Analyzer to analyze headers, correlate SPF result and DKIM outcomes, and spot authentication issues.
• Phishing Link Checker and TouchPoint to support phishing prevention and email-based threats analysis.

Many platforms integrate record checker utilities, SPF test runners, and an SPF raw checker. Vendors like EasyDMARC and MxToolBox often appear on G2 Crowd, SourceForge, Channel Program, and Expert Insights; review feedback to select an online tool that matches your risk level, reporting needs, and alerting preferences. For managed environments, MSP Program offerings help standardize SPF configuration and periodic monitoring across client portfolios, with failures report insights enabling prompt resolution.

Best practices:

• Schedule periodic monitoring to query domain records, validate SPF compliance, and perform diagnostic tests after any SPF configuration change.
• Use a domain scanner to discover shadow senders; verify each authorized IP and include, and remove stale entries to reduce security risk.
• Pair SPF with DMARC enforcement for fraud prevention and domain authentication at scale, improving email deliverability and reducing delivery issues.

By embedding a disciplined SPF record check routine—complete with SPF validator reviews, SPF record lookup automation, and continuous diagnostics—you harden email security, safeguard sender identity, and sustain the email delivery performance your brand and customers expect.

The Food and Drug Administration announced Tuesday a recall of bags of certain dog treats over concerns about potential salmonella contamination.

Elite Treats, based in Florida, issued a recall of a single lot of 6-ounce bags of Elite Treats Chicken Chips for Dogs, according to the FDA.

The recalled bags have lot number 24045 and an expiration date of April 2027.

The dog treats were sold to Florida Hardware, which distributed the items to feed stores in Alabama, Florida, Georgia, North Carolina and South Carolina.

The contamination was discovered after testing performed by a third-party laboratory identified contamination in a related yet commercially unreleased lot of the same product, the FDA said.

No illnesses have been reported thus far from the treats.

The FDA said salmonella can cause illness in pets eating the products.

Pets with salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever and vomiting, and some pets may have a lower appetite and abdominal pain, the agency said. Pet owners should contact a veterinarian if their animal has eaten the recalled product and has these symptoms or if they are concerned that the pet may be infected.

The agency said pets can be infected without showing symptoms because infected pets, even if they do not show symptoms, can act as carriers and transfer salmonella through their feces and saliva into the home and to people and other pets in the household.

People can also become exposed through multiple ways, the FDA said, including handling the contaminated products, contact with pets who have eaten the product or contact with surfaces that have touched contaminated food, such as bowls, utensils or countertops.

The risk of human illness from salmonella-contaminated pet food rises if people do not thoroughly wash their hands after handling the food or having contact with their petor by not thoroughly cleaning contaminated surfaces, the FDA warned.

Salmonella can cause serious and sometimes deadly infections in people, according to the agency. Healthy people infected with salmonella should monitor themselves for symptoms, which can include nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever. In rare incidents, salmonella can lead to more serious issues, such as arterial infections, endocarditis, arthritis, muscle pain, eye irritation and urinary tract symptoms.

Young people, the elderly and people with weak immune systems are more vulnerable to infection, the FDA said. People who have symptoms after coming into contact with the recalled product or a pet that has eaten the product are urged to contact their healthcare providers.

Consumers are urged to stop using the recalled treats. They are told to dispose of the product in a way that children, pets and wildlife cannot access it.

“Wash and sanitize pet food bowls, cups and storage containers,” the FDA’s recall alert said. “Always ensure you wash and sanitize your hands after handling recalled food or any utensils and surfaces that come in contact with recalled food.”

Customers may contact Elite Treats for information about how to request a refund.
