Emailservice is a Spring Boot based tool that provides convenient email sending capabilities by integrating with QQ Mail’s SMTP service. It is designed for developers who need to add automated email dispatch to their applications or MCP-based workflows.
Download or clone the project, package it as a JAR file using Maven or Gradle, and place the resulting Email-service-0.0.1-SNAPSHOT.jar in your project root. Obtain a 16‑character SMTP authorization code from QQ Mail’s settings, then configure the MCP server with the --qq.username and --qq.password arguments.
Check that the mailbox address format is correct, the SMTP authorization code is accurate (case‑sensitive), and that SMTP service has been enabled in QQ Mail settings.
Log in to QQ Mail web, navigate to Settings → Account → POP3/IMAP/SMTP service, enable the service, and follow the prompts to get a 16‑character code. This is not your QQ login password.
