//是否HTML形式发送
mail.IsBodyHtml = true;
//附件
if (fujian.Length > 0)
{
mail.Attachments.Add(new Attachment(fujian));
}
//邮件服务器和端口
SmtpClient smtp = new SmtpClient(server, 25);
smtp.UseDefaultCredentials = true;
//指定发送方式
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
//指定登录名和密码
smtp.Credentials = new System.Net.NetworkCredential(username, password);
//超时时间
smtp.Timeout = 10000;
smtp.Send(mail);
return "send ok";

static void Main(string[] args)
{
CreateMessageWithAttachment(@"服务器抵制");
}
public static void CreateMessageWithAttachment(string server)
{
// Specify the file to be attached and sent.
// This example assumes that a file named Data.xls exists in the
// current working directory.
string file =@"E:\补充数据库设计的系统设计\法规备案审查管理子系统-系统设计说明书.doc";
//创建邮件并指定收件人
MailMessage message = new MailMessage("发信人邮箱","收信人邮箱");
message.BodyEncoding = Encoding.Default;
message.Subject = "just a test";
//创建附件
Attachment data = new Attachment(file);
//为福建文件添加标记
ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(file);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(file);
disposition.ReadDate = System.IO.File.GetLastAccessTime(file);
//添加附件
message.Attachments.Add(data);
//发送邮件
SmtpClient client = new SmtpClient(server);
// Add credentials if the SMTP server requires them.
client.Credentials = CredentialCache.DefaultNetworkCredentials;
client.Send(message);
// Display the values in the ContentDisposition for the attachment.
ContentDisposition cd = data.ContentDisposition;
Console.WriteLine("Content disposition");
Console.WriteLine(cd.ToString());
Console.WriteLine("File {0}", cd.FileName);
Console.WriteLine("Size {0}", cd.Size);
Console.WriteLine("Creation {0}", cd.CreationDate);
Console.WriteLine("Modification {0}", cd.ModificationDate);
Console.WriteLine("Read {0}", cd.ReadDate);
Console.WriteLine("Inline {0}", cd.Inline);
Console.WriteLine("Parameters: {0}", cd.Parameters.Count);
foreach (DictionaryEntry d in cd.Parameters)
{
Console.WriteLine("{0} = {1}", d.Key, d.Value);
}
Console.Read();
data.Dispose();
}

利用jmail组件发送邮件还是可以的，大多数邮箱都能收到！
163、126、sina、sohu、hotmail等，yahoo的不太好！

搜索jmail发送邮件,有很多有效的代码！
