git-multimail includes a built-in self-check mechanism: when the hook script is invoked with the environment variable GIT_MULTIMAIL_CHECK_SETUP set to a non-empty string, it prints out the resolved configuration values (administrator, charset, email prefix, FQDN, project description, pusher, repository path, and repository short name), verifies that standard input works correctly, and reports whether git-multimail appears to be properly configured (or flags missing required settings, such as no configured email recipients). This behavior is documented in the official git-multimail troubleshooting guide. The variable must be set to a non-empty value — an empty string has no effect — and the correct variable name is GIT_MULTIMAIL_CHECK_SETUP, not GITHUB_MULTIMAIL_CHECK_SETUP.
