Features
The feature list from the plugin's own readme on WordPress.org, trimmed to the essentials.
- Password reset and new user notices to the administrator — the user still gets their reset link and their welcome email, only the copy to the admin stops
- Automatic update reports — core, plugins and themes, separately
- Comment notifications — awaiting moderation, and new comment to the post author
- Nothing is hidden from you — a notification you switch off is never created, so it will not appear in the Email Logs either, and the screen tells you that
- Account recovery is never at risk — the emails users need to regain access to their account are deliberately out of reach of this screen
- Off means off, on stays on — installing or updating the plugin never silences an email your site was already sending

Ideal for solving problems with emails that are not sending (forms, etc.)
This plugin is really simple but very useful to solve all the problems related to php mail() function. I use it with Amazon SES but they work with any SMTP server. It has fixed issues on many of my websites. And what's more, it's free, unlike the others!
