Since I wanted to comply with current state of things, I've made a modified ErrorHandlerMiddleware to check on the session context, before deciding, what to do with the issue. See the example below:

This way, basic exceptions, like NotFoundException, MissingRouteException or AuthSecurityException will not be sent, when there is no user in the request context (in this case, session storage for cakephp 3.x AuthComponent)

<?php

namespace App\Middleware;

use App\Model\Entity\User;
use App\Traits\EmailThrowableTrait;
use Cake\Controller\Exception\AuthSecurityException;
use Cake\Http\Exception\InvalidCsrfTokenException;
use Cake\Http\Exception\NotFoundException;
use Cake\Http\ServerRequest;
use Cake\Routing\Exception\MissingRouteException;
use Throwable;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

class ErrorHandlerMiddleware extends \ErrorEmail\Middleware\ErrorHandlerMiddleware
{
    use EmailThrowableTrait;

    private function middlewareSkipEmail(?Throwable $exception, ?ServerRequest $request, ?ResponseInterface $response)
    {
        $userdata = $request->getSession()->read('Auth.User');
        if (!empty($exception) && (empty($userdata) || !($userdata instanceof User))) {
            // skip emailing for these errors if it's unauthenticated (no user) request
            $exception_class = get_class($exception);
            switch ($exception_class) {
                case MissingRouteException::class:
                case InvalidCsrfTokenException::class:
                case NotFoundException::class:
                case AuthSecurityException::class:
                    return true;
            }
        }
        return false;
    }

    /**
     * Add email funcitonality to handle exception
     *
     * @param Exception $exception The exception to handle.
     * @param ServerRequestInterface $request The request.
     * @param ResponseInterface $response The response.
     * @return ResponseInterface A response
     */
    public function handleException($exception, $request, $response)
    {
        if (!($request instanceof ServerRequest) || !$this->middlewareSkipEmail($exception, $request, $response)) {
            // Add emailing throwable functionality
            $this->emailThrowable($exception);
            // Use parent funcitonality
        }
        return $this->_callParent($exception, $request, $response);
    }
}
