📝 SummarySummary by CodeRabbit
WalkthroughThe push-email workflow now runs for branch pushes, preserves concurrent runs, limits notification jobs to five minutes, and uses a pinned SMTP notification action. ChangesPush email notifications
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The notification workflow can still email on branch deletions without commit information, and email delivery may fail if the configured SMTP service does not provide implicit TLS with AUTH PLAIN. Confirm the SMTP endpoint and exclude deleted events before merging. Suggested reviewers: Poem

github.event.deleted to be false, preventing deleted-branch push events from
running the notification job while preserving notifications for normal pushes.

GitHub Actions push event branches filter deleted branch push payload deleted true head_commit null official documentation
💡 Result:
When a branch is deleted on GitHub, it triggers the push webhook event with the deleted attribute set to true [1][2]. In this scenario, the head_commit object in the event payload is typically null because there is no head commit associated with a deleted branch [1][2]. To filter out workflows triggered by branch deletions, you can use a conditional if statement in your workflow job configuration to check the payload data. Example configuration to skip jobs when a branch is deleted: jobs: my_job: runs-on: ubuntu-latest if: ${{!github.event.deleted }} steps: - name: Run on push run: echo "This only runs for non-deletion pushes." Alternatively, if you need to specifically handle or ignore branch deletions, you can access the deleted boolean directly from the github.event context [1][2]. Key points regarding the GitHub Actions push event and deletions: - Branch deletion triggers a push event [3][4]. - The deleted property in the event payload will be true [1][2]. - The head_commit field is null when the branch is deleted [1][2]. - GitHub Actions branch filters (e.g., on: push: branches: [...]) do not prevent the workflow from triggering upon deletion of a branch if that branch matches the filter; they only determine which branches cause the workflow to trigger when they are pushed to or deleted [3][5]. Therefore, using an if condition is the standard way to programmatically ignore deletion events [4].

Exclude deleted branch pushes.
branches: ['**'] does not exclude branch-deletion push events. These events set github.event.deleted to true and github.event.head_commit to null, so the job can send a notification without a commit message. Add !github.event.deleted to the job condition.

💡 Result:
The repository hyperpolymath/smtp-notify-action does not appear to be a widely documented or standard public GitHub Action, and the specific commit hash (ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7) does not surface in general search results. Hyperpolymath repositories often use standard, maintained alternatives like dawidd6/action-send-mail or step-security/action-send-mail for SMTP notifications [1][2][3]. Regarding the technical aspects of using AUTH PLAIN with STARTTLS: 1. Security of AUTH PLAIN with STARTTLS: AUTH PLAIN is considered secure only if the SMTP connection is already encrypted via STARTTLS or implicit TLS (SMTPS) [4][5]. When STARTTLS is correctly implemented, the connection is upgraded to an encrypted state before the authentication credentials (which are essentially sent in plaintext in the PLAIN mechanism) are transmitted [4]. 2. Risk of Man-in-the-Middle (MitM) Attacks: There is a known risk where a malicious actor can perform a MitM attack to downgrade or intercept the STARTTLS negotiation, potentially forcing an unencrypted connection [4]. To mitigate this, secure email implementations should either enforce TLS (disabling STARTTLS in favor of implicit TLS on port 465) or, if using STARTTLS, verify the server certificate and ideally reject the connection if encryption cannot be established [4][5][6]. 3. Best Practices in GitHub Actions: - Always use established, audited actions (e.g., dawidd6/action-send-mail) rather than custom scripts [1][7][8]. - Ensure the 'secure' or 'tls' option is set to true in the action configuration [1][9][7][10]. - Prefer port 465 (implicit TLS) over port 587 (STARTTLS) if the SMTP provider supports it, as it removes the risk of a plaintext downgrade during the handshake [9][7][8][4]. - Never store credentials in plaintext; always use GitHub Secrets [1][2][10]. If you are auditing code that uses a custom action or script for SMTP, ensure that the connection logic specifically requires encryption before calling the authentication/login method, as some implementations may mistakenly permit login over an unencrypted connection [6].

Use an SMTP endpoint that supports implicit TLS.
The action receives secure: true and sends AUTH PLAIN over implicit TLS. It does not implement STARTTLS. If SMTP_PORT is 587 or the server requires another authentication mechanism, the notification step can fail. Confirm an implicit-TLS endpoint, normally on port 465, with AUTH PLAIN.
