MxToolbox provides a suite of network diagnostic and monitoring tools, including DNS lookups, blacklist checks, and email health analysis.
Tools
Lookup Bimi Record
Retrieves BIMI (Brand Indicators for Message Identification) record and diagnostic information for a domain. BIMI allows organizations to display verified logos in email clients. This tool checks: - Whether a BIMI record exists at default._bimi.{domain} - DMARC policy requirements (quarantine or reject needed for BIMI) - DNS resolution details and nameserver information - Related diagnostic checks and recommendations Returns comprehensive lookup data including passed/failed checks, DMARC records, DNS transcript, and related lookups. Use when verifying email branding configuration or troubleshooting BIMI implementation.
Lookup Blacklist
Tool to perform a blacklist check on a domain or IP. Use when you need to verify whether a domain or IP is listed in common blacklists.
Lookup Dkim Record
Tool to retrieve DKIM (DomainKeys Identified Mail) records for a domain. DKIM is an email authentication method that helps prevent email spoofing by allowing the receiver to verify that an email was actually sent and authorized by the owner of that domain. Use this tool to verify DKIM configuration and troubleshoot email authentication issues.
Lookup Dmarc Record
Retrieves DMARC (Domain-based Message Authentication, Reporting & Conformance) records for a domain and performs validation checks. Returns detailed information about the DMARC record including policy settings (reject/quarantine/none), reporting addresses, alignment modes, and diagnostic check results. Useful for verifying email authentication configuration and troubleshooting email delivery issues.
Lookup Dns Records
Performs comprehensive DNS health check and retrieves name server records for a domain. Returns detailed diagnostics including: - Name server (NS) records with IP addresses, TTL, and status - DNS configuration health checks (warnings, errors, passed tests) - Query transcripts showing DNS resolution path - Related lookup suggestions (A, MX, SPF records) Use this to diagnose DNS issues, verify name server configurations, or check DNS propagation status.
Http Lookup
Tool to perform an HTTP test on a domain. Use when you need to assess HTTP connectivity and status for a given domain.
