无法在asp.net中发送mailmessage

以下代码无法向客户发送电子邮件，也不会抛出任何exception。 代码不发送任何电子邮件或exception但已执行。我对asp.net完全陌生。 有人可以帮我解决问题。

码：

try { String userName = "ramesh"; String passWord = "123456"; String sendr = "[e-mail]"; String recer = "[e-mail]"; String subject = "Comformation "; String body = "Dear Customer"; MailMessage msgMail = new MailMessage(sendr, recer, subject, body); int PortNumber = 25; SmtpClient smtp = new SmtpClient("smtp.test.com", PortNumber); msgMail.IsBodyHtml = true; smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Credentials = new System.Net.NetworkCredential(userName, passWord); smtp.Send(msgMail); MsgLP.Text = "Emailed to Customer.."; LogInLink.Visible = true; } catch (Exception ex){ AuditLog.LogError("ErrorE-mail " + ex.Message); }

您必须设置smtp.EnableSsl=true并使用端口号587 。 你的最终代码是这样的：

 try { String userName = "ramesh"; String passWord = "123456"; String sendr = "[e-mail]"; String recer = "[e-mail]"; String subject = "Comformation "; String body = "Dear Customer"; MailMessage msgMail = new MailMessage(sendr, recer, subject, body); int PortNumber = 587; //change port number to 587 SmtpClient smtp = new SmtpClient("smtp.gmail.com", PortNumber); //change from test to gmail smtp.EnableSsl = true; //set EnableSsl to true msgMail.IsBodyHtml = true; smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Credentials = new System.Net.NetworkCredential(userName, passWord); smtp.Send(msgMail); MsgLP.Text = "Emailed to Customer.."; LogInLink.Visible = true; } catch (Exception ex){ AuditLog.LogError("ErrorE-mail " + ex.Message); } 

我用我的凭据测试了这段代码，它运行正常。

  System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage(); mm.From = new MailAddress("[e-mail]"); mm.To.Add("[e-mail]"); System.Net.Mail.Attachment attachment; string strFileName; strFileName = "Uploadfile/" + "200814062455PM_Admin_Screenshot (10).JPEG"; attachment = new System.Net.Mail.Attachment(Server.MapPath(strFileName)); mm.Attachments.Add(attachment); mm.Body = ("
Hi

"); ; mm.IsBodyHtml = true; mm.Subject = "Candidate " + Name + " for your Requirement " + Jobtt + " "; System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587); client.UseDefaultCredentials = false; client.Credentials = new System.Net.NetworkCredential("[e-mail]", "password"); client.Port = 587; client.Host = "smtp.gmail.com"; client.EnableSsl = true; object userstate = mm; client.Send(mm);
