Prostyle SMTP configures the WordPress PHPMailer through official WordPress hooks. It focuses on classic SMTP delivery with freely configurable host, port, encryption, authentication, sender settings, test emails, local mail logs and understandable diagnostics.
The plugin does not require a cloud mail API, does not add telemetry, does not display advertising and does not include upsells. It can be used with hosting relay configurations as long as the hosting provider accepts mail through the configured SMTP settings.
The SMTP password is encrypted locally with AES-256-GCM and WordPress salts. Email message bodies and attachment contents are never stored by the mail log.
Each wp_mail() call can receive a request-local Request ID and a unique Trace ID. Normal emails run without SMTP debugging. Detailed SMTP diagnostics are captured only for explicitly started diagnostic test emails and are redacted before display or download.
Prostyle SMTP does not retry, queue or resend emails. A successful SMTP hand-off means that the configured mail server accepted the message; it does not guarantee inbox placement.
Privacy
Prostyle SMTP can store a local technical mail log when logging is enabled. The log can include timestamps, delivery status, SMTP metadata, the mail origin, attachment count, masked or full recipient addresses depending on the selected setting, and optionally the email subject.
New installations use masked recipient storage by default and do not store email subjects by default. Administrators can disable logging, change recipient storage, enable or disable subject storage, set a retention period, limit the maximum number of log entries, delete logs and export CSV files.
Email message bodies, HTML content, plain text content, attachment contents, attachment paths, SMTP passwords and authentication data are not stored in the mail log.
Diagnostic exports are generated only after an administrator action. They are designed to exclude passwords, authentication headers, cookies, nonces, tokens, full server paths and email message bodies. Theme and plugin lists are disabled by default for new installations and can be enabled by administrators for support cases.
The plugin does not add telemetry and does not send diagnostic data to Prostylemedia or third-party services automatically.
Assets and Licensing
The plugin code is licensed under GPLv2 or later. The included Prostylemedia logo assets were created for Prostylemedia and are included by the plugin author for use with this GPL-compatible plugin distribution. No third-party JavaScript or CSS libraries are bundled.
Uninstall
Deactivating the plugin keeps settings and logs. Deleting the plugin through WordPress runs uninstall.php and removes plugin-owned settings, transients, database tables, cron hooks, metadata and plugin-owned files.
