Configure a secure SMTP server for WordPress email delivery.

== Description ==

aSMTP mailer routes WordPress email through an authenticated SMTP server instead of the default PHP mail function. It keeps the interface minimal while providing the controls needed for reliable transactional email delivery.

== Features ==

* SMTP host, port, authentication, username, and password settings.
* TLS, SSL, and no-encryption transport options.
* From email and From name controls.
* Force From name, email, or full address for outgoing messages.
* Reply-To address and display name controls.
* Optional logs for WordPress `wp_mail()` delivery attempts.
* Test email screen with redacted SMTP analysis for developers.
* Secure TLS defaults with automatic port suggestions.
* SMTP connection test for credentials without sending an email.
* Optional plain-text to HTML conversion with text alternative preservation.

== Security Notes ==

* Admin actions require WordPress capabilities and nonces.
* Settings inputs are sanitized and constrained before saving.
* Password values are encrypted with WordPress salts when OpenSSL is available and are never displayed after saving.
* SMTP test analysis redacts likely credentials and tokens.
* Delete confirmation is handled by an external JavaScript file.
* Reset actions are scoped per tab instead of clearing unrelated settings.

== Installation ==

1. Upload the `asmtp-mailer` folder to `/wp-content/plugins/`.
2. Activate `aSMTP mailer` from the WordPress Plugins screen.
3. Go to Settings > aSMTP mailer and enter SMTP credentials.
4. Send a test email to verify the configuration.

== Frequently Asked Questions ==

= Does this plugin keep existing SMTP Mailer settings? =
