I wrote a WCF service for sending mail in Silverlight:
using System.Web.Mail;
MailMessage msg = new MailMessage();
msg.From = emailFrom;
msg.To = emailTo;
msg.Subject = msgSubject;
msg.Body = msgBody;
msg.Priority = MailPriority.High;
SmtpMail.Send(msg);
success = true;
This works fine in localhost, but when I host it in IIS, it doesn't show any error, but no mail has been received. What may be the problem?
Try to set the smtpserver property for the smtpmail class before you call the send method.

I am using System.Net.Mail.SmtpClient to send mail in my Xamarin Form app. It's set to using my gmail address, and working great.
I would like to get the error from the smtp server (if there is one) to inform the user.
So, I am using the event _SendCompleted
Here my code
(sending email)
MailMessage mail = new MailMessage();
SmtpClient smtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress(outils.emailEmetteur);
mail.To.Add("toto#outlook.frfr");//Tiers.contactEmail);
mail.Subject = outils.emailObjetDefaut;
mail.Body = outils.emailMessageDefaut;
bool fileExist = File.Exists(filePath);
if (fileExist)
{
Attachment pJ = new Attachment(filePath);
mail.Attachments.Add(pJ);
smtpServer.Port = 587;
smtpServer.Host = "smtp.gmail.com";
smtpServer.EnableSsl = true;
smtpServer.UseDefaultCredentials = false;
smtpServer.Credentials = new NetworkCredential(outils.emailEmetteur, outils.emailEmetteurMDP);
try
{
smtpServer.SendAsync(mail, null);
smtpServer.SendCompleted += smtpServer_SendCompleted;
return true;
}
catch (Exception ex)
{
}
}
(send completed event)
private static void smtpServer_SendCompleted(object sender, AsyncCompletedEventArgs e)
{
string token = (string)e.UserState;
string info = "";
if (e.Cancelled)
{
info = "Send canceled.";
}
if (e.Error != null)
{
info = e.Error.ToString();
}
else
{
info = "Message sent.";
}
}
I am trying to send an email to an incorrect address (toto#outlook.frfr)
My event is correctly triggered, but e.Cancelled and e.Error are NULL, and, in my Gmail inbox, I receive an error from smtp server telling me that the email address was incorrect, and that what I want to get in my Xamarin app.
Do you have any idea ? Thanks :)
Your client relays it to Gmail's outgoing mail server; the transaction to submit the message to SMTP is successful. The error only happens later, when Gmail tries to connect to the recipient's mail server, and can't resolve it; at that point, your client is no longer necessarily connected, and so the mail server generates a bounce message and delivers it to the sender's inbox.
In the general case, you either have to write your own mail server (but no, don't go there) or examine the inbox for bounce messages.
I have an exchange account. I need to send an email with it. I tried sending with SmtpClient and it fails. I have few questions after googling
What are the things needed to send email with an exchange account?
What's difference between WebDav and MAPI? Which should be used?
Any Ideas?
Here is my code. I think this can't be done with SMTP.
MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress("sender#domain.com", "Sender");
mailMessage.To.Add("receiver#domain.com");
mailMessage.Subject = "Test Exchange Email";
mailMessage.Body = "Sameple test message";
SmtpClient smtp = new SmtpClient("Exchange Server Url");
smtp.EnableSsl = true;
smtp.Port = 465;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("username", "pwd");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(mailMessage);
I am trying to send Email from an asp.net webform using Gmail.
the code works from my machine but when I upload the code to my windows server 2012 in Azure I get
Unable to connect to Remote Server - exception
here is my code:
MailMessage mail = new MailMessage();
mail.Subject = "Subject";
mail.Body = "Main body goes here";
mail.From = new MailAddress("myAcount#gmail.com");
mail.IsBodyHtml = true;
mail.BodyEncoding = System.Text.Encoding.Unicode;
mail.SubjectEncoding = System.Text.Encoding.Unicode;
mail.To.Add("aaaa#gmail.com");
NetworkCredential cred = new NetworkCredential("myAccount#gmail.com", "myPwd");
SmtpClient smtp = new SmtpClient("smtp.gmail.com");
smtp.EnableSsl = true;
smtp.Credentials = cred;
smtp.Port = 587;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(mail);
Any ideas?
Make sure the local VM's Firewall rules are permitting outgoing connection via port 587. Here is a good article on how to create outbound Firewall rule.
I am trying to get the classic ASP page working with Outlook (Microsoft Web Email) SMTP relay. I am getting the following error :
CDO.Message.1 error '80040213'
The transport failed to connect to the server.
My code looks like
dim objEmail
Set objEmail = Server.CreateObject("cdo.message")
objEmail.To = list
objEmail.From = "xyz#abc.com"
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = smtpServer
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = username
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = password
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
objEmail.Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60

objEmail.Send
I tested with GMAIL and this thing snippet works fine with it. I guess I am missing something in configuration of Outlook SMTP
Here is an example that does work. Make sure that the account you use has a mailbox, and the from adress is indeed the account adress.
ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;
var msg = new MailMessage();
msg.Subject = "Hello";
msg.Body = "Hello Sir";
msg.From = new MailAddress("no.reply#contoso.com");
msg.To.Add("user#contoso.com");
var client = new SmtpClient("smtp.outlook.office365.com");
client.Port = 587;
client.Credentials = new NetworkCredential("no.reply#contoso.com", "******");
client.EnableSsl = true;
client.Send(msg);
I am trying to send mail using SmtpClient and below is my code.
SmtpClient client_ = new SmtpClient("relay-hosting.secureserver.net", 25);
//client_.DeliveryMethod = SmtpDeliveryMethod.Network;
//client_.EnableSsl = true;
// client_.UseDefaultCredentials = false;
//client_.Credentials = new System.Net.NetworkCredential(_fromAddress, _password);
MailAddress from_ = new MailAddress(_fromAddress, _fromName);
MailMessage msg_ = new MailMessage(from_, from_);
msg_.Subject = "Subject";
StringBuilder body_ = new StringBuilder();
body_.AppendLine("Line1");
body_.AppendLine("===============================================================================================");
body_.AppendLine("Line2");
body_.AppendLine("===============================================================================================");
body_.AppendLine("line2");
body_.AppendLine("===============================================================================================");
msg_.Body = body_.ToString();
msg_.IsBodyHtml = true;
client_.Send(msg_);
I am getting TimeOut error. When Same smtp configuration using in email client on my machine, it send the mail immediately. I don't know what can be cause. Also when I used my Gmail account with gmail smpt server it worked.
Most consumer ISPs block port 25 to prevent you from running a mail server.
Therefore, you cannot connect to port 25 from your house.
You can ask them for an alternate port.
Try port 587; it's commonly used as well.
