SMTP

Send, test, and debug SMTP mail flows with safe dry runs, provider-aware auth, and deliverability checks.

This skill is coherent and appears to do what it says: SMTP diagnostics with a strong emphasis on safety. Before installing or using it, note that it will create ~/smtp/ and persist debugging context there — review and control that directory (permissions are set by the setup instructions). Never put passwords or tokens into those files; provide credentials via a secret manager or a one-time runtime prompt as the skill recommends. Confirm any live send explicitly (the SKILL.md requires it), and if you prefer no persistent local state, avoid running setup or delete ~/smtp/ after use. If you have strict policies about autonomous agent actions, remember the platform allows autonomous invocation by default — ensure you or your org consent to the agent being able to run this skill when appropriate.

Type: OpenClaw Skill Name: smtp Version: 1.0.0 The SMTP skill bundle is a well-structured tool designed for debugging and managing email flows with a strong emphasis on safety and user consent. It implements multiple guardrails, such as mandatory 'canary' test sends, explicit confirmation gates for live emails, and strict prohibitions against storing credentials in local memory files (~/smtp/). The instructions in SKILL.md and setup.md prioritize diagnostic accuracy and security best practices, including the use of standard networking tools (swaks, openssl) and restricted file permissions (chmod 600).
