Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/vitaliikaplia/kaplia-smtp/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.

It does one thing: configures WordPress mail to use your own SMTP server.
No ads, no usage tracking, no weekly reports, no scheduled marketing email.
Features
- SMTP host, port, encryption, username, password.
- Forced From email/name and Return-Path support.
- Test email from the settings page.
- Optional debug logging to the PHP error log.
- Import from old WP Base theme SMTP options.
- Automatic import from WP Mail SMTP and deactivation of WP Mail SMTP / WP Mail SMTP Pro.
- Optional
KAPLIA_SMTP_*constants for project-level config.
