C将电子邮件“从”地址更改为用户提供的地址

我把你介绍给杰夫·阿特伍德 编码恐怖 关于以编程方式发送电子邮件的文章。它详细描述了您应该采取的步骤,以防止您的电子邮件被垃圾邮件过滤器等抓获…

Jeff Atwood's Coding Horror: So You'd Like to Send Some Email (Through Code)

我使用这个代码:

public static bool sendEmail(string fromName, string fromEmail, string body, string subject, string toEmail) {

    String strReplyTo = fromEmail.Trim();
    String strTo = toEmail;
    String msgBodyTop = "Email from: " + @fromName + "(" + @fromEmail + ")\n"
            + "" + " " + DateTime.Now.ToLongTimeString()
            + " FROM " + HttpContext.Current.Request.Url.ToString + " : \n\n"
            + "---\n";

    MailMessage theMail = new MailMessage(fromEmail, strTo, subject, msgBodyTop + body);

    theMail.From = new MailAddress(strReplyTo, fromName);

    SmtpClient theClient = new SmtpClient(ConfigurationManager.AppSettings["SMTP"].ToString());

    theClient.Send(theMail);

    return true;
}

似乎对我有用…

在和我们的操作人员讨论并尝试了atomiton的方法之后,我发现这对我们来说实际上是不可能的。
