Trace Mail Log

Trace Mail Log provides complete visibility into your Drupal site's outgoing emails. It works with Symfony Mailer, Mail System, or Drupal core mail to capture every email event, storing the full SMTP conversation so you can verify delivery and troubleshoot issues.

Unlike simple mail catchers, this module doesn't just intercept emails—it logs them as they flow through your actual mail transport, capturing real mail server responses.
