This plugin provides a simple API for storing miscellaneous log entries and their overview in admin area (or network 
admin area, if activated on a multisite).
Developed for private use (heavily used by my other plugins), but has perspective for more extensive usage. I can’t guarantee any support in the future nor further development, but it is to be expected. Kindly inform me about bugs, if you find any, or propose new features: <a href="mailto:zaantar@zaantar.eu?subject=[wordpress-logging-service]" rel="nofollow ugc">zaantar@zaantar.eu</a>.
See Usage and FAQ for more information.

WordPress Logging Service

Provides a simple API for storing miscellaneous log entries and their overview in admin area.

webaware

Log emails to the WordPress database for later analysis. Access is restricted to administrators, and emails with WordPress passwords are obfuscated for security / privacy. Useful for diagnosing lost email problems.
Use this plugin with <a href="https://shop.webaware.com.au/downloads/disable-emails/" rel="nofollow ugc">Disable Emails</a> to divert all WordPress emails into logs, especially handy for developers.
Logs are automatically purged after a defined period, set through a settings page in the WordPress admin. Setting the period to 0 prevents logs from being purged. Uninstalling the plugin purges all logs.

Log Emails

Thanks for a plguin, it was thoroughly coded and seems have all that I need.

Simple and useful plugin

Seriously, this plugin is so freakin' helpful. I work on a lot of sites that I have set up on my local development machine and don't have outgoing email set up on purpose. Only rarely do I need access to test those emails. But when I need it, it's typically urgent. This plugin has completely saved the day multiple times over the past month.

Thank you so much for the great work!

Only sad I didn't find this plugin sooner!

I've checked it's functionality and with first sight, it didn't contained vulnerable parts. Thank you.

compact and free from vulnerabilities
