发送电子邮件会发出SSLProtocolException

标签: android email ssl-certificate sendmail

我正在使用此示例代码:

http://www.jondev.net/articles/Sending_Emails_without_User_Intervention_%28no_Intents%29_in_Android

我正在尝试使用自己的服务器电子邮件来发送电子邮件,而不是专注于Android。

我知道该示例配置为仅适用于Gmail。

我改变了:

    _host = "smtp.myserver.com"; // default smtp server 
    _port = "587"; // default smtp port 
    _sport = "587"; // default socketfactory port 

,这在MainActivity上:

Mail m = new Mail("username@myserver.com", "password"); //to my sever email

我只是在Outlook上设置了正确的信息,它可以工作,我可以通过这封电子邮件发送和接收。

服务器允许此设置:

POP3 SMTP IMAP 邮局 移动/ PDA

问题:

我需要添加/更改更多内容吗?或者此示例无法与其他gmail一起使用。

我在Logcat上遇到了这个错误:

答案 0 :(得分:3)

我从来没有使用过这个包装器,但代码假设SSL支持,而你的端口587服务器似乎不支持SSL。注释掉这两行

props.put("mail.smtp.socketFactory.port", _sport); 
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 

并将此行设置为false为true

props.put("mail.smtp.socketFactory.fallback", "false"); 

这可能有所帮助。
