原文外掛簡介
Mesh SMTP is a lightweight WordPress SMTP plugin for website owners who want a clear way to configure outgoing email without a crowded dashboard.
Connect WordPress to Gmail, Google Workspace, Microsoft 365, Zoho Mail, Hostinger Email, SendGrid, Mailgun, or any custom SMTP server. The guided setup explains each field in plain language and separates mailer acceptance from real inbox delivery.
Mesh SMTP works with email sent through WordPress wp_mail(), which commonly includes:
Contact form notifications
Password reset emails
New user and administrator notifications
WooCommerce transactional emails
WordPress update and security notifications
Messages sent by compatible themes and plugins
Easy 3-Step WordPress SMTP Setup
Choose your email provider from simple provider cards.
Enter the SMTP connection details with clear host, security, port, authentication, username, password, and sender guidance.
Send and confirm a test email so the dashboard does not claim delivery before you verify the inbox.

Honest Test Email Results
A successful wp_mail() response means WordPress and PHPMailer accepted the sending request without returning an error. It does not prove that the message reached the Inbox.
Mesh SMTP therefore uses a two-part verification flow:
Accepted by mailer — WordPress returned no sending error.
Received and confirmed — an administrator checked the Inbox or Spam folder and confirmed receipt.
This avoids a misleading “delivered” message when the receiving mail server may still delay, filter, or reject the email.
Privacy-First Email Logs
Email logging is configurable. The recommended default stores failed emails only, masks recipient addresses, hides subject lines, and removes old entries after 14 days.
Mesh SMTP never stores email bodies or attachments in its activity log.
Supported Provider Presets
Gmail and Google Workspace
Outlook and Microsoft 365
Zoho Mail
Hostinger Email
SendGrid
Mailgun
Custom SMTP
Microsoft 365 Note
Some Microsoft 365 tenants do not allow username/password SMTP. OAuth 2.0 or an administrator-enabled SMTP AUTH policy may be required. Mesh SMTP currently supports standard SMTP credentials and displays a warning when the Microsoft preset is detected.
Secure wp-config.php Constants
Developers can define these constants in wp-config.php to override values saved in WordPress:
MESHSMTP_ENABLED
MESHSMTP_HOST
MESHSMTP_PORT
MESHSMTP_SECURE
MESHSMTP_AUTH
MESHSMTP_USERNAME
MESHSMTP_PASSWORD
MESHSMTP_FROM_EMAIL
MESHSMTP_FROM_NAME
The SMTP password is never shown back in the admin interface.
