You haven't mentioned which version of Silverstripe 4 you're using, so I'll assume it's one of the latest minor releases.

Since 4.4.0 (I think) Silverstripe does not write to the default LoggerInterface handler for core error handling, allowing you to use it for custom app logging instead. If you're a version from 4.4 onwards, and you want to send application errors to your mail handler, you will need to use the Psr\\Log\\LoggerInterface.errorhandler instance instead:

SilverStripe\Core\Injector\Injector:
  Psr\Log\LoggerInterface.errorhandler:
    ...    

You should also ensure that you've correctly configured your email driver .
