Javax邮件异常 [英] Javax Mail Exception

问题描述

你好
我不知道问题出在哪里，但是我正在将Netbeans 6.9.1与tomcat 6.0.2一起使用，并且有一个邮件库试图发送电子邮件，但是在方法上给了我一个错误:Transport.send( message );
sendEmail(sSMTP, sFrom, sEmail, sSubject, sMessage);
并在网页上显示:
Could not connect to SMTP host: <hostname>, port: 25</hostname>
能否请您提供任何建议.
它在Netbeans/tomcat上给我一个例外:

Hello
I don''t know where the problem is but I am using netbeans 6.9.1 with tomcat 6.0.2 and have a mail lib trying to send an email but gives me an error on the method: Transport.send( message );
sendEmail(sSMTP, sFrom, sEmail, sSubject, sMessage);
and on the webpage it gives me:
Could not connect to SMTP host: <hostname>, port: 25</hostname>
Can you please give any advices.
It gives me an exception on Netbeans/ tomcat:

连接被拒绝.

请检查您的电子邮件服务器.它们有时具有禁止"功能.它会执行应做的事情-禁止您进行一定数量的错误登录尝试.

这可能真的很烦人，特别是在开发过程中.

还要检查禁令期间是否设置了规则"，有些规则会将禁令作为服务器的简单限时规则来处理.

The connection is refused.

Please check your email-server. They sometimes have a ''ban'' function. It does what it''s supposed to do - it bans you with a certain number of false login attempts.

This can be really annoying, specially while development.

Also check if there are "rules" set up during ban, some handle the ban as a simple limited time rule for the server.
