对于遵循以下格式的电子邮件地址，我收到了RFC 2822，3.6.2错误（仅限生产中）：abc@xyz.co.uk
源代码如下：
Mail::to($emailAddress, $name)->send($email);
通过Laravel验证的其他电子邮件格式工作正常。
我无法在本地重现此问题
我正在使用laravel 5.3
本地： Windows 10 + homestead + mailtrap
生产： AWS + forge + mailgun
Swiftmailer版本是5.4.8（从composer.lock中检索）
我可以使用Firefox V：54.0（32位）在本地重现它。这看起来很奇怪，我无法在本地使用Chrome重现它。 以下是完整的例外：
