When I enable the module and do not change the default configs, I get deprecated php errors when the module sends error/exception emails:
Deprecated function: trim(): Passing null to parameter #1 ($string) of type string is deprecated in Drupal\exception_mailer\Subscribers\ExceptionEventSubscriber->getConfigFormEmailAdress() (line 224 of .../exception_mailer/src/Subscribers/ExceptionEventSubscriber.php)
Deprecated function: trim(): Passing null to parameter #1 ($string) of type string is deprecated in Drupal\exception_mailer\Logger\ErrorLog->getConfigFormEmailAdress() (line 227 of .../exception_mailer/src/Logger/ErrorLog.php)
Add verification for the existence of Email recipient address.

As we discussed with @szato, it would be better to fix the config.
Here is the patch for that.
