在我的GMail中：

from: myGmail@gmail.com  
subject: hello admin  
content: welcome!

我想将“myGmail@gmail.com”更改为“user1341”。

from: user1341
subject: hello admin  
content: welcome!

我该如何解决？

String sender将sender作为InternetAddress：

此类使用RFC822的语法表示Internet电子邮件地址。典型的地址语法格式为＆＃34; user@host.domain"或＆＃34;个人姓名＆＃34;。

因此，您的InternetAddress＆＃34; user1341＆＃34;无效且被忽略。

要解决您的问题，请使用有效的sender，这意味着为其提供符合RFC的user@host.domain，格式为{{1}}。
