Stops outgoing emails sent from WordPress. This plugin stops
outgoing emails generated by WordPress core, plugins, and themes.
Emails sent using the wp_mail() function, will not be sent.
In the case where an author does not use the recommended wp_mail()
function and instead sends the email using another mechanism, an email will
still be sent.

This plugin allows you to suspend sending emails when doing development work.
Any calls to wp_mail() will fail silently. WordPress
will operate as if the email were sent successfully
but no email will actually be sent.

On the admin menu page Settings > Stop Emails, there is the option
to log all emails to the PHP error log. By default this logging is
disabled.

NOTE: If using the PHP mail() function directly, this
plugin will NOT stop the emails.

Built by Sal Ferrarello / @salcode

Lies! The email wasn't really sent, we're running Stop Emails

Where do the emails go?

The emails are lost forever.

Why are some of my emails still being sent?

Most likely, this is due to a plugin you have running.
There are two different things the plugin could be
doing to cause emails to still be sent.

The plugin is overriding our overriding of the sending mechanism.
The plugin is calling the PHP function mail() directly.

Unfortunately in either of these cases, this plugin will not be able to stop
the email.

Known Incompatible Plugins?

A list of Known Incompatible Plugins is available at https://github.com/salcode/stop-emails/wiki/Known-Incompatible-Plugins.

I want to log the emails that are stopped

You can enable logging of stopped emails on the
admin menu page Settings > Stop Emails.

Emails will be logged to your PHP error log.

Why would I want install in the mu-plugins directory?

Activating a plugin normally requires logging into the site.
Installing the file in the mu-plugins directory allows you to
activate the plugin without logging in. This can be
helpful when setting up an existing site locally.
