Question

我使用java.security（使用Java 8）文件在Play网络服务器（2.5.x + Scala）上禁用了TLS版本，如下所示：

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, MD5withRSA, DH keySize < 768, \
    EC keySize < 224, 3DES_EDE_CBC

使用此更改（TLSv1），我无法将电子邮件发送到smtp.gmail.com:465。我正在使用播放邮件程序版本5.0.0。 application.conf文件中的设置：

host = smtp.gmail.com
port = 465
ssl = yes

我收到以下错误：

Answer 1

问题已解决。参考：https://github.com/playframework/play-mailer/issues/150

简而言之：通过系统属性配置ssl协议。

Answer 2

这看起来像预期的行为。您将收到协议被禁用的例外。您期望什么行为？

无法使用Play-Mailer 5.0禁用TLS v1.0（使用Play 2.5.x）
