This code sample uses System.Web.Mail, which was deprecated when .NET 2.0 was released. See http://msdn.microsoft.com/en-us/library/system.web.mail.aspx. Please update using the recommended namespace System.Net.Mail. Thanks!

RESPONSE: Yes, you may wish to use system.net.mail if you wish. The link should be included on the Microsoft page we are referencing -

http://www.systemnetmail.com/faq/4.2.aspx

This KB is here to provide a quick reference as to what type of code should be used as there are many different ways to send mail through our servers.

-- since I just had to put this together, thought I'd offer up a simple copy/paste helper to save someone some time. I agree with Roger that we ought to use the system.net mail goodies. HTH. LP


public static void CreateAndSendEmailMessage()
{
string to = "EMAIL ADDRESS BEING SENT TO - CAN ALSO BE A COLLECTION OF ADDRESSES";
string from = "EMAIL ADDRESS FROM";
string subject = "EMAIL SUBJECT GOES HERE";
string body = @"EMAIL BODY GOES HERE";
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(from, to, subject, body);
System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();
message.Priority = System.Net.Mail.MailPriority.Normal;

//THIS NEXT FOUR LINES ARE IN CASE YOU NEED MORE CONTROL OVER SPECIFICS AND CANNOT USE THE web.config FILE OPTION
//PASSWORD SHOULD BE SEEN AS A SECURITY RISK SO USING ENCRIPTION WOULD BE IDEAL - THESE ARE ALL HANDLED BY web.config INCLUDING THE client.Credentials LINE. SWEET STUFF IMHO.
//System.Net.NetworkCredential netwrkCrd = new System.Net.NetworkCredential();
//netwrkCrd.UserName = "VALID ARVIXE EMAIL USER NAME";
//netwrkCrd.Password = "VALID ARVIXE EMAIL USER NAME'S PASSWORD";
//client.Credentials = netwrkCrd;

try
{
client.Send(message);
}
catch (Exception ex)
{
Console.WriteLine("Exception caught in CreateAndSendEmailMessage(): {0}", ex.ToString());
}
}

hiLlewellyn,
thx for the example , but where i can write smtp details and port address if i m not going to use web.config settings

Hi Arvand,
I am working for Techdata client and creating an application in which I need to send a mail if a user clicks forget password link in my application. Our company's applications are hosted in ARVIXE. I have checked the sample mail sending code in the Arvixe support community and found that "localhost" is been used as host for the SMTP Server. But this is not working. I am getting an error message as "The SMTP server requires a secure connection or the client was not authenticated. The server response was : SMTP authentication is required.". Please help me

What is the smtpClient address?

here is the code that will work for sure.

C#
-----------
using System.Net.Mail;

MailMessage EmailMsg = new MailMessage();
EmailMsg.From = new MailAddress("[email protected]");
EmailMsg.To.Add(new MailAddress("[email protected]"));
EmailMsg.Subject = "Customer_Questions";
EmailMsg.Body = "your Customers body";
EmailMsg.IsBodyHtml = true;
EmailMsg.Priority = MailPriority.Normal;
EmailMsg.BodyEncoding = Encoding.UTF8;
SmtpClient MailClient = new SmtpClient("mail.namannassar.com", 25);
MailClient.UseDefaultCredentials = false;
MailClient.Credentials = new NetworkCredential("[email protected]", "passcode");
MailClient.Send(EmailMsg);

Now you MUST use System.Net.Mail not System.Web.Mail or it won't work!

It worked as expected with your suggested change, thank you!

did any one try to send email from asp.net using System.Net.Mail on any arvixe server using 587 or 465 and SSL enabled, my code works fine on gmail using port 587 and SSL , but when i replace mail server to any of my accounts on arvixe , 465 always time out and 587 always "server dose not support secure connection , if i disable ssl it works on 587, same code works fine on port 25.
Appreciate any help.

I tried the above example, and mine didn't work.
Not sure if I have my email server correct.
string _from = "[email protected]";
SmtpClient smtp = new SmtpClient("mail.allergy-acupuncture.com");
smtp.Credentials = new System.Net.NetworkCredential(Convert.ToString(_from), "passcode");
smtp.UseDefaultCredentials = false;
// smtp.Host = "smtp.strawberry.arvixe.com";
smtp.Send(mail);
return smtp;

I tried code like this with port 25 and host localhost didn't work.

Change

smtp.Credentials = new System.Net.NetworkCredential(Convert.ToString(_from), "passcode");
smtp.UseDefaultCredentials = false;

order.

Write

smtp.UseDefaultCredentials = false;

before.

Hello,
Please help me.
My website was developed by somebody. due to some dispute we have taken that website's source code and paste it to other website hosting provider. This website was developed in VB as a project. Now the problem is following:
There is a inquiry page in website. I want as any visitor submit their inquiry, one notification should come to my email ID from a given email ID. Currently it is happening but Email(from) notification is coming on my email ID is my developer's email ID. I want to remove his email ID and put my email ID. I have searched all source code but i could not find that email ID from which i am receiving notification.
Kindly help me. Please remember website is in Visual basic, language C#.
Thanks in advance.

Can someone please help me? The code below is what I've used on my site, but I seem to not be able to get any email sent from the site page. When someone visits site, I have a contact page that allows visitors to select a email button. If they click the button, it takes them to a page where they can fill out their email address, subject, and message. The code below is what I have attached to the submit (email) button to send the email. I receive no error code in Visual Studio or on the site. According to everything the email gets sent, but of course I never receive it in my inbox. Do I need to add something to the web.config file to help this code work? I'm at a lost and would appreciate any help.
Thanks,
Charity

you can try c# cdo email instead of smtp

Anyone get the solution for SSL email using port 465? I typically use GMAIL to handle sending/receiving my email but now I need a small app that resides on one of my machines to just send.

I can get port 587 to work just fine with a standard, non encrypted email. The minute I use port 465 and EnableSsl = true I get a timeout. Not an error connecting or sending, but a timeout (as if it can't find the port). Is there something special I need to do for my network credentials?

smtp.UseDefaultCredentials = false;
smtp.Credentials = new System.Net.NetworkCredential("[email protected]", "password");

Any help is appreciated. Thanks!

Richard Rubin....did you ever get this working? I cannot get an outbound email to work for anything. Not non encrypted or SSL enabled. Same results as everyone else. It appears to successfully send but the email never shows up.

what is the number of e-mails of hours?
Can i send 461 emails on time or send 100 and more 100....?

I was able to send emails via .Net

First I set up a mail account from my control panel.
For example, I created a mail account "[email protected]" with the password "OhHai!Kthxbai"

C# code to send emails using this account :

using System.Net.Mail;

using (MailMessage mailMessage = new MailMessage())
{
mailMessage.To.Add(ToAddress);
mailMessage.From = new MailAddress(FromAddress);
mailMessage.Subject = Subject;
mailMessage.Body = Body;

client = new SmtpClient();
client.UseDefaultCredentials = false;
client.Host = "mail.domain.com";
client.Port = 26;
client.Credentials = new System.Net.NetworkCredential("[email protected]", "OhHai!Kthxbai");
client.Send(mailMessage);
}

Hope this helps.
