Java 什么Apache Commons电子邮件服务器在本地主机上工作？

我试图从一台在Apache上运行Tomcat的开发计算机发送电子邮件。我在Windows上开发，但其他人在Macintosh或Linux上开发。我无法确定要使用哪个主机和端口。我不知道密码是从哪里来的

public void sendPackage(String toEmailAddress, String subject, String content)
{
    Url url = ((WebRequest)RequestCycle.get().getRequest()).getUrl();
    String fullUrl = RequestCycle.get().getUrlRenderer().renderFullUrl(url);
    if (fullUrl.toLowerCase().contains("localhost"))
    {
        sHost = "localhost";    //"smtpout.secureserver.net";
        iPort = 465;    //25;   //9090; 
        sFrom = "info@mywebsite.com";
    }
    else
    {
        sHost = "mail.mywebsite.com";
        iPort = 587;
        sFrom = "mail@mywebsite.com";
    }

    try
    {
        Email email = new SimpleEmail();
        email.setDebug(true);
        email.setHostName(sHost);
        email.setSmtpPort(iPort);
        email.setAuthenticator(new DefaultAuthenticator(sFrom, "tuscul312"));
        email.setSSLOnConnect(true);
        email.setFrom(sFrom);
        email.setSubject(subject);
        email.setMsg(content);
        email.addTo(toEmailAddress);
        email.send();
    }
    catch (EmailException eex)
    {
        logger.error("sendPackage failed: " + eex);
        eex.printStackTrace();
    }
}

堆栈跟踪显示

及

这个硬编码的配置应该工作吗？

其他地方有服务器设置吗？

好。我刚刚为localhost添加了一个旁路，并将尝试确定服务器需要哪些配置设置。

虽然Windows可能没有本地SMTP服务器，但基于Unix的O/S仍需要SMTP中继。你不能再从任何地方发送到任何地方了——开放SMTP中继的日子早已一去不复返了。不过，你可以使用Gmail——更多细节请参见。
