Simple SMTP Mailer

Send emails via SMTP using the msmtp command-line tool configured in ~/.msmtp/config for authentication and server settings.

This skill appears to do what it says: run the msmtp CLI using your ~/.msmtp/config. Before installing, consider: 1) the agent will use whatever SMTP credentials are in that file — prefer app-specific passwords and minimal-permission accounts; 2) review and secure ~/.msmtp/config (chmod 600) and avoid placing highly privileged credentials there; 3) be aware the agent can send arbitrary outbound emails (a potential data-exfiltration channel); 4) the CLAUDE.md includes a hardcoded home path (/Users/yugaoxiang/.msmtp/config) — the real config is ~/.msmtp/config on your system; 5) avoid following the advice to disable TLS certificate checks in production. If you only need to send occasional messages, consider manually running msmtp or creating a narrowly scoped SMTP account for the skill rather than exposing your primary email credentials.

Type: OpenClaw Skill Name: simple-smtp-mail Version: 1.0.0 The skill provides instructions and command templates for using the legitimate 'msmtp' utility to send emails. It includes standard installation steps and security recommendations, such as setting restrictive permissions on configuration files. While CLAUDE.md contains a hardcoded absolute path (/Users/yugaoxiang/.msmtp/config) that appears to be a developer oversight from the author's local environment, there is no evidence of malicious intent, data exfiltration, or prompt injection.
