[development] Email on error

I've looked around drupal.org and couldn't find any modules that do what I'm looking for so I just figured I'd ask here before just writing my own. But I'm looking for a module that will allow me to have Drupal send me an email any time an error occurs and also has the ability to let me trigger my own errors (I know I could use trigger_error() but often times for these custom errors I want to be notified but don't want the error showing up on screen). I know I can do this relatively easily but was trying to see if something was already written that allows for this before committing myself to it.
