SPFtoolbox is a self-hosted web application for checking DNS, mail and domain information from a browser. It brings a collection of small diagnostic operations into one interface, which is handy when troubleshooting a domain without repeatedly switching between command-line utilities and separate web services.
Despite its name, the program is not limited to SPF-related work. The available operations cover ordinary DNS records, mail-policy checks, reverse lookups, registration data and network tests. That broader scope makes it useful as a lightweight internal toolbox for support teams and administrators who want commonly used checks available from a shared web application.
This is free and open source software.
Key Features
- Looks up A, AAAA, MX, TXT and HINFO records for a supplied domain or host.
- Can request a broader set of DNS information when a single record type is not enough.
- Checks DMARC information used in email authentication policy.
- Performs reverse DNS lookups for investigating an IP address.
- Provides WHOIS lookups for domain and registration information.
- Checks addresses against DNS-based blacklist services used when investigating mail delivery problems.
- Includes TCP port checking for basic reachability tests alongside DNS diagnostics.
- Runs as a browser-accessible application, allowing a team to expose the same diagnostic tools from a central installation.
