在tomcat中发送Java电子邮件数小时后失败

Question

我使用亚马逊SES服务在Tomcat6中发送电子邮件。它只能发送电子邮件成功几个小时，然后它将发送电子邮件失败。如果我重新启动tomcat6，它会再次发送电子邮件成功几个小时，然后失败。这个问题已经困扰我好几天了。
有没有人遇到过这个问题？请帮帮我，谢谢。

        this.userName = username;
        this.password = password;

         return new PasswordAuthentication(userName, password);

看起来它忽略了您的starttls属性。尝试修复常见的JavaMail错误，看看是否有帮助。

您使用的是什么版本的JavaMail？
