.Net使用SmtpClient发送邮件，报错：不允许使用邮箱名称。服务器响应为: xxxw

从网上找了一个封装.Net的Smtp邮件发送的类

[csharp]
class MailSender
{
    private MailMessage mailMessage;
    private SmtpClient smtpClient;
    private string password;//发件人密码

    /// <summary>

    public MailSender(string To, string From, string Body, string Title, string Password)
    {
        mailMessage = new MailMessage();
        mailMessage.To.Add(To);
        mailMessage.From = new System.Net.Mail.MailAddress(From);
        mailMessage.Subject = Title;

使用某些邮箱的时候会报错（如sohu）：不允许使用邮箱名称，服务器响应为: xxx。需要设置单独的用户名，故修改了下，并做了一些优化。如下：

[csharp]
class MailSender
{
    private readonly MailMessage mail;
    private readonly string password;//发件人密码
    private readonly string user;

    /// <param name="sendAccount">发件人账号</param>
    /// <param name="sendPassword">发件人密码</param>
    public MailSender(string to, string from, string body, string subject, string sendAccount, string sendPassword)
    {
        mail = new MailMessage();
        mail.To.Add(to);
        mail.From = new MailAddress(from);
        mail.Subject = subject;
        mail.Body = body;
        mail.IsBodyHtml = true;
        mail.BodyEncoding = System.Text.Encoding.UTF8;
        mail.Priority = MailPriority.Normal;
        this.password = sendPassword;
        this.user = sendAccount;
    }
    /// <summary>

    /// </summary>
    public void Attachments(string path)
