RFC 2822,3.6.2使用Laravel「[email protected]」格式生成電子郵件時出現錯誤

Question

我得到RFC 2822,3.6.2錯誤（僅在生產中）對於遵循此格式的電子郵件地址：abc@xyz.co.uk​

源代碼如下：

Mail::to($emailAddress, $name)->send($email); 

其他電子郵件格式，通過Laravel驗證工作就好了。

我不能重現此問題在本地

我使用laravel 5.3

地方： 的Windows 10 +宅基地+ mailtrap

生產： AWS +鍛造+ mailgun

Swiftmailer版本是5.4.8（從composer.lock檢索）

我可以使用Firefox V：54.0（32位）在本地重現它。這看起來很奇怪，我無法在本地使用Chrome在生產中重現它。 以下是完整的例外：

確保

• FROM，TO和答覆人字段有效，工作電子郵件地址
• 域名是有效
• 沒有空格或地址中的其他奇怪字符（您是否檢查過沒有非ASCII字符在字符串中看起來像ASCII？）

你檢查PHP錯誤日誌嗎？
