通过SMTP发送邮件时出现“MessagingException：无法将套接字转换为TLS”

标签： java smtp javamail starttls

使用 JavaMail 通过 SMTP（+ STARTTLS）发送邮件时，会引发以下异常：

javax.mail.MessagingException: Could not convert socket to TLS;
nested exception is:
javax.net.ssl.SSLException: java.lang.ArrayIndexOutOfBoundsException

这里的多个帖子（在stackoverflow上）和其他地方建议邮件传输会话的一些属性，即

props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.ssl.trust","*");

在解决这个问题上发挥了作用，但我已经尝试了这些参数的所有组合（存在/不存在），并且它们都没有解决问题。

有人知道如何解决这个问题吗？

其他信息/详情：

Java版本：1.6.0

JavaMail版本：1.5.2

邮件传输会话的属性：

props.put("mail.transport.protocol","smtp");
props.put("mail.smtp.host","XXX");
props.put("mail.smtp.port","587");
props.put("mail.smtp.auth","true");
props.put("mail.smtp.starttls.enable","true");
props.put("mail.smtp.ssl.trust","*");
props.put("mail.smtp.user","XXX");
props.put("mail.smtp.password","XXX");
props.put("mail.smtp.connectiontimeout","60000");
props.put("mail.smtp.timeout","600000");
props.put("mail.smtp.writetimeout","60000");

从JavaMail调试输出（在引发异常之前）：

看起来JDK的SSL支持出了问题。也许来自服务器的证书有些令人困惑。您正在使用相当旧版本的JDK。我会尝试升级到当前版本，看看是否能解决问题。您还可以尝试在JDK中启用一些低级SSL调试输出，如JavaMail SSLNOTES.txt中的链接所述。

也许您的JavaMail库（mail.jar或javax.mail.jar）太旧了。 从此处下载最新版本：https://javaee.github.io/javamail/
