Laravel使用SwiftMailer发送邮件时如何捕获SMTP会话错误

我尝试向虚假邮箱地址发送邮件，当该邮箱地址无效、邮件无法投递时，无法捕获对应的错误。在SMTP服务器日志中我观测到如下记录：

Fri 2020-12-11 12:08:58.582: 03: --> 250-STARTTLS
Fri 2020-12-11 12:08:58.582: 03: --> 250 SIZE
Fri 2020-12-11 12:08:58.582: 02: <-- MAIL FROM:<my_email@mydomain.com>
Fri 2020-12-11 12:08:58.583: 03: --> 250 2.1.0 Sender OK
Fri 2020-12-11 12:08:58.583: 02: <-- RCPT TO:<somefakeaddress@mydomain.com>
Fri 2020-12-11 12:08:58.584: 03: --> 550 5.1.1 Recipient unknown <mi@f
Fri 2020-12-11 12:08:58.585: 02: <-- RSET
Fri 2020-12-11 12:08:58.585: 03: --> 250 2.0.0 RSET? Well, OK
Fri 2020-12-11 12:08:58.586: 02: <-- QUIT
Fri 2020-12-11 12:08:58.586: 03: --> 221 2.0.0 See ya in cyberspace
Fri 2020-12-11 12:08:58.586: 04: SMTP session terminated (Bytes in/out

但在我的Laravel应用中，即便按照Laravel 7官方文档的说明使用了邮件事件监听器，依然无法捕获该错误。

此外，执行如下代码没有任何返回：

Mail::to('somefakeaddress@mydomain.com')->send(new Mailable($mail_data));

请问有什么办法可以在Laravel中捕获SMTP会话的错误？
