是用微軟自帶的 System.Net.Mail 來發(fā)送郵件。 代碼如下。 ??????? /// <summary>??????? /// 發(fā)送郵件??????? /// </summary>??????? /// <param name="strSmtpServer">郵件服務(wù)器地址</param>??????? /// <param name="UserName">發(fā)送人郵件用戶名只需前面部分 如 123@qq.com 123 即為用戶名</param>??????? /// <param name="Password">郵件密碼</param>??????? /// <param name="strFrom">發(fā)送方郵件地址</param>??????? /// <param name="strto">接收方郵件地址</param>??????? /// <param name="strSubject">主題</param>??????? /// <param name="strBody">內(nèi)容</param>??????? /// <param name="authentication">是否進(jìn)行身份驗(yàn)證</param>??????? /// <returns>bool</returns>??????? public static bool SendToMail(string strSmtpServer, string UserName, string Password, string strFrom, string strto, string strSubject, string strBody)??????? {??????????? try??????????? {??????????????? System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(strSmtpServer); ??????????????? client.UseDefaultCredentials = true;//是否身份驗(yàn)證??????????????? client.Credentials = new System.Net.NetworkCredential(UserName, Password);//身份驗(yàn)證賬號(hào)密碼? 主要賬號(hào)無需后綴名如 123@qq.com? 只需填寫123 即可。 ??????????????? client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;??????????????? //client.EnableSsl = true;??????????????? System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strFrom, strto, strSubject, strBody);??????????????? message.BodyEncoding = System.Text.Encoding.GetEncoding("gb2312");??????????????? message.SubjectEncoding = System.Text.Encoding.GetEncoding("gb2312");??????????????? message.IsBodyHtml = true;??????????????? message.Priority = System.Net.Mail.MailPriority.High;??????????????? client.Send(message);??????????????? return true; ??????????? }??????????? catch (Exception ex)??????????? {??????????????? ErrorLog.WriteError(ex.Message.ToString());??????????????? return false;??????????? }??????? } 如果將?//client.EnableSsl = true; Ssl 加密注釋掉就可以發(fā)送成功。如果啟用了這段斷面 就發(fā)送不了。高手幫忙。
