SMTP configuration
Connect an authenticated SMTP account with TLS/STARTTLS or SSL/SMTPS. Unauthenticated SMTP is available when allowed by your server.
Features · v1.2.3
Everything you need for reliable SMTP configuration.
A focused suite of WordPress email tools: provider setup, meaningful diagnostics, branded tests and privacy-conscious logs.
Email infrastructure
Built around real WordPress email workflows.
Every feature below is included in the installable v1.2.3 package.
Smart provider selection
Choose Google, Microsoft 365 or Others. Provider selection fills its hostname; Others unlocks fully custom hostname entry.
Professional test email
Send a premium branded HTML test message with a plain-text alternative. Check receipt with your destination mailbox.
AJAX activity filtering
Review accepted or failed send attempts without a full admin-page reload. Pagination and browser navigation are supported.
Encrypted credentials
SMTP password data is stored encrypted using AES-256-GCM when PHP OpenSSL is available and keyed from your WordPress salts.
Configuration diagnostics
Check SMTP readiness, OpenSSL, saved credentials, log storage and scheduled cleanup status from one read-only diagnostics screen.
Local log retention
Choose 7, 14, 30 or 90 days of log retention. WordPress cron handles scheduled cleanup when it runs.
Sender controls
Configure From Email and From Name, optional sender override and return-path behavior from the admin interface.
Transport insights
See logged attempts, accepted attempts, failures and an acceptance rate for transport outcomes—not inbox placement.
Built on WordPress
Works through PHPMailer configured by wp_mail(). Avoid running multiple plugins that override the same mail transport.
What this plugin does not do
Clear expectations, from the start.
SMTP Connect does not operate a mail server, provide an email inbox or override your provider's restrictions. It uses your selected SMTP service.
- Google and Microsoft OAuth are not included.
- Successful transport acceptance does not guarantee inbox delivery.
- Email account or SMTP service is not included.
- Scheduled log cleanup depends on functioning WordPress cron.
