ASP.NET 用JAMIL组件发布电子邮件
;?? ASP NET 网站开发邮件发送用的比较多的是用JAMIL组件 下面我来说说具体的用法 ??? 首先 我们要从网上下载Jamil dll的组件 然后添加引用using jmail 然后再本机或者服务器上注册一下??? 将jmail dll拷贝到服务器的system 目录下 开始 运行 cmd 输入regsvr jmail dll ??? protected void sendMail(String sender String senderMail String receiver String subject String content)??? {??? jmail MessageClass jmMessage = new jmail MessageClass();??? //设置字符集??? jmMessage Charset = gb ;??? //信件的contentype 缺省是 text/plain ） : 字符串如果你以HTML格式发送邮件 改为 text/HTML 即可 ??? Jmail ContentType = text/HTML ;??? //发件人邮箱地址??? jmMessage From = senderMail;??? //发件人姓名??? jmMessage FromName = sender;??? //设置主题??? jmMessage Subject = subject;??? //设置内容??? jmMessage Body = content;??? // 设置收件人邮箱??? jmMessage AddRecipient(receiver );??? // string[] arraymail = MailTo Split( ; );??? // for (int i = ; i arraymail Length; i++)??? // {??? //Jmail AddRecipientBCC(arraymail[i] );??? //? }??? // 设置登陆邮箱的用户名和密码??? jmMessage MailServerUserName = ;??? jmMessage MailServerPassWord = ****** ;??? //设置 *** tp服务器地址??? if (jmMessage Send( false))??? {??? Response Write( scriptalert( 发送成功 )/script );??? }??? else??? Response Write( scriptalert( 发送失败 )/script );??? }??? 好的OK了！ lishixinzhi/Article/program/net/201311/11624
asp.net 发送邮件,我看那些网站上给别人发送邮件都是输入邮箱号码并未输入邮箱密码
怎么可能需要输入密码呢。。。呵呵
就是你使用一个邮箱（可以是个人，也可以是企业），通过
asp.net
编写的程序像客户的邮箱发送邮件。在网上看看asp.net发送邮件的代码吧！
如何用asp.net实现“给qq邮箱发送邮件”？
在标签中添加代码。
配置Web.config,在configuration标签中添加以下代码，（aaaaaaaaaa：表示发信人的邮箱号.bbbbbbbbbb：表示前面获取的授权码.端口号port：我测试25能发，而465不能发。
具体代码如下：
system.net
mailSettings
smtp deliveryMethod="Network" from="nekorz lt;1018472917@qq.comgt;"
network host="smtp.qq.com" userName="aaaaaaaaaa@qq.com" password="bbbbbbbbbb" port="25" enableSsl="true" /
/smtp
/mailSettings
/system.net
添加发送邮件代码：
MailMessage myMessage = new MailMessage();
myMessage.Subject = "Test Message";
myMessage.Body = "这是一封测试邮件.";
myMessage.To.Add(new MailAddress("aaaaaaaaaa@qq.com", "昵称"));
SmtpClient mySmtpClient = new SmtpClient();??????? try
{
mySmtpClient.Send(myMessage);
} ? ? ? ?catch (SmtpException ex)
{
}
asp.net怎么发送6万封邮件，请教高手。
1.把邮件按域名分类，如163邮箱一组、gmail的一组……
2.然后对每一组的邮件采用密送的方式，即多个帐号之间用分号
为了提高速度，同时可以使用多线程
