『壹』 用javaMail发邮件时出现下面的错误是怎么回事 SMTPSendFailedException: 554 DT:SPM 126 smtp7
554 DT 表示163的服务器端认为你发出的邮件为垃圾邮件，并不是你的代码出了问题。如果可以的话，建议用一些不是很大众化的邮箱地址去实现Java后台发邮件。
『贰』 javamail发邮件始终报javax.mail.NoSuchProviderException:smtp错误
可能是版本问题！ 如果你用的MyEclipse的话右键Build Path->config build path->add library J2EE1.4或者上网下载mail.jar
你的代码没问题！或者给你个例子：

『叁』 用java写的邮件发送程序
界面自己写一下就可以了，把相关的参数传进去就可以了。 这个是我以前写的。用的javamail。 有main方法，测试一下自己的邮件，应该没问题的。希望可以帮到你。注意导入你需要的javamail.jar的包 -------------------------------------------------------------- package com.fourpane.mail; import java.util.Properties;

props.put("mail.smtp.host", host); props.put("mail.smtp.auth", "true"); Session session = Session.getDefaultInstance(props); session.setDebug(true); MimeMessage msg = new MimeMessage(session); try { msg.setFrom(new InternetAddress(from));

} } /** * reply mail */ public static void replyMail() { //test } } 注意：此实现要求邮箱都支持pop3和smtp协议。现在老的网易邮箱都支持（2006年以前注册的），所以的sina的 qq的都可以，雅虎的部分支持，具体的可以在网上搜下把。 ============================================================================== 还有一种办法，也是我以前用到的。 其实最简单的发邮件方式是用Apache的Common组件中的Email组件，封装得很不错。 特简单。首先从Sun的网站上下载JavaMail框架实现，最新的版本是1.4.1。然后是JavaBeans Activation Framework，最新版本1.1.1，JavaMail需要这个框架。不过如果JDK是1.6的话就不用下了。1.6已经包括了JavaBeans Activation Framework。 最后从 http://commons.apache.org/email/ 下载最新的Common Email，版本1.1。 首先在Eclipse中建立一个新的Java工程，然后把JavaMail和Common Email解压缩，在工程中添加解压缩出来的所有Jar的引用。 代码： package org.fourpane.mail; import org.apache.commons.mail.EmailException; import org.apache.commons.mail.HtmlEmail; public class Mail { public static void main(String[] args) { //SimpleEmail email = new SimpleEmail(); HtmlEmail email = new HtmlEmail(); email.setHostName("smtp.163.com");//邮件服务器 email.setAuthentication("xingui5624", "******");//smtp认证的用户名和密码 try { email.addTo("[email protected]");//收信者 email.setFrom("[email protected]", "******");//发信者 email.setSubject("xingui5624的测试邮件");//标题 email.setCharset("UTF-8");//编码格式 email.setMsg("这是一封xingui5624的测试邮件");//内容 email.send();//发送 System.out.println("send ok.........."); } catch (EmailException e) { e.printStackTrace(); } } } 【如果发送不成功，可能是你的jar包问题，javamail 的jar可能和jdk1.5以上的j2ee的jar冲突。还有就是可能你的邮箱不支持pop3和smtp协议。】
