Laravel不发送电子邮件而不发送错误

I've been on a project for the past four months now and I am really pissed at what am facing with Laravel right now. It's not sending emails; I set it up to use the mail driver and put in the right code, but it seems not to work at all. Besides not working, it doesn't even give me an error!I've been on a project for the past four months
