more sensible defaults

1. Make it easier to trace bounced/failed emails back to this package using [email protected]
2. In fact, I would even disable slack by default, because
   • the error Driver [slack] not supported. is very vague when FAILED_JOB_SLACK_WEBHOOK_URL is not provided, no indication it is caused by this package
   • I suspect among those who install this, lesser of them have a slack webhook URL

Thanks, but I'm going to leave the email like it is for now.

Feel free to submit a PR to fix the default behavior of the slack messages.

ok thanks, submitted the other PR

I have to say, both config defaults result in very vague errors, its odd to me to fix the other but not this.

For this email one, I only know when I see a bunch bounced emails in my inbox (after failed jobs which don't occur all the time).

But since [email protected] is so generic, I assumed it was from Laravel, until I realized that not all projects have this error.

The mystery is only solved when I thought much harder and decided to search my code for [email protected].

Config defaults in general should not trigger any unhappy paths, hope you will reconsider thanks.
