Stars SMTP Mailer

描述

Every email your WordPress website sends is important — whether it’s a contact form message, password reset, order update, or newsletter. These emails help you stay connected with your users, build trust, and keep your business running smoothly.

But by default, WordPress uses a basic PHP mail function — and that often leads to problems. Emails may get blocked by your hosting server, flagged as spam, or never arrive at all. You may not even know anything went wrong.

That’s where our SMTP plugin makes a difference.

It replaces the unreliable default method with SMTP (Simple Mail Transfer Protocol) — the same trusted system used by major email services like Gmail, Outlook, SendGrid, Mailgun, and more. It sends your messages through real, authenticated mail servers for secure, consistent delivery — every time.

New in Version 2.3

🔒 Stronger Password Encryption:
SMTP passwords are now encrypted using a unique per-site key derived from your WordPress security salts — replacing the old hardcoded key. A random IV is generated for every encryption operation (AES-256-CBC). Existing passwords are automatically migrated on first load with no action required.

📊 Brand-New Dashboard:
The plugin now has a fully redesigned Dashboard page with:
– Stat cards showing today’s emails, 7-day accepted/failed counts, and success rate
– An interactive bar chart (Chart.js) for email activity over the last 7 days
– A “Recent Emails” table showing the last 5 log entries at a glance
– An active SMTP account panel with quick Edit and Send Test links
– An Overview sidebar showing account count, log usage (with a warning at 180/200), and plugin version
– Quick Actions panel for one-click access to Add Account, Send Test Email, View Logs, and Export CSV

📥 Export & Clear Logs:
Email logs can now be exported as a CSV file directly from the Email Log page or the Dashboard. A nonce-protected “Clear Logs” button lets you wipe all log entries with one click. A confirmation notice is shown after clearing.

🔍 Advanced Log Filtering:
Filter email logs by status (Accepted / Failed) and type (Test / General) using new dropdown selectors on the Email Log page.

❗ Log Cap Warning:
A dashboard notice and admin-bar warning appear when the email log reaches 180 of 200 entries, prompting you to export or clear old data before entries are auto-pruned.

🛡️ SSRF Protection:
SMTP hostname validation now blocks Server-Side Request Forgery attempts by rejecting loopback, private (RFC-1918), link-local, and reserved IP ranges before any connection is made.

🖥️ WordPress Dashboard Widget:
A new widget on the main WordPress Dashboard displays a 7-day sent/failed bar chart, today’s email count, and the currently active SMTP account — at a glance without leaving the dashboard.

🔐 Security Hardening:
– AJAX actions now require the manage_options capability and verify CSRF nonces
– Account add/edit form processing moved to admin_init to prevent headers-already-sent warnings and enable proper redirect after save
– Unauthenticated access to the notify/subscribe endpoint removed; rate limiting (one request per user per hour) added
– All form inputs consistently sanitized and validated

📬 Weekly Email Reports (introduced in 2.2.1, refined in 2.3):
Your site automatically sends a visual weekly summary of email activity to the site admin — includes total emails sent, last week’s count, and percentage change.

What is SMTP and Why You Need It

SMTP (Simple Mail Transfer Protocol) is the global standard for sending emails. It’s how major providers like Gmail, Yahoo, Outlook, and others securely deliver billions of emails every day.

In contrast, WordPress’s default PHP mail is unverified and often blocked. SMTP ensures your messages come from a verified email server, improving both trust and deliverability.

With SMTP, you get:
– Higher email delivery success rates
– Fewer emails lost or sent to spam
– Improved domain reputation
– Consistent, professional communication

If your WordPress site sends any type of email — SMTP is essential.
