Your toAddress or username ('from' address), or both, is an empty string. You need to use a real email address there. Look at the value used in line 50 of EmailUtility.java and make sure it is not empty.
您的 toAddress 或用户名（“发件人”地址）或两者都是空字符串。您需要在那里使用真实的电子邮件地址。查看 EmailUtility.java 的第 50 行中使用的值并确保它不为空。

I have the same error. In my case issue was with empty email address. So it was not null, but just empty string with length=0. I've added additional validation to resolve this issue.
我有同样的错误。就我而言，问题是电子邮件地址为空。所以它不是空的，而是长度为 0 的空字符串。我添加了额外的验证来解决这个问题。

In my case when I got this error, I had ccmail address left blank in server.properties file. So, make sure addresses values exists and they're valid.
在我遇到此错误的情况下，我cc在 server.properties 文件中将邮件地址留空。因此，请确保地址值存在且有效。
