Web Forms :: Sending Email To The Users Using Smtp Client And MailMessage Class?
Apr 16, 2010
am sending email to the users using smtp client and MailMessage class.i have been adding the addresses of multiple receivers in the to property of the object of MailMessage class. the problem is that the receiver can see the email addresses of other receipents. is there any way to hide the email addresses of other receipents.i mean setting some property or something like that.otherwise i will be left with only option to send individual email to the users.

I've written a simple webservice and am running it locally to test it out. Right now, my settings are as follows:
From [URL]
Settings When Hosted Externally
<system.net>
<mailSettings>
<smtp from="noreply@domain.net">
<network host="smtpout.secureserver.net" password="<password>" port="25" userName="noreply@domain.net"/>
</smtp>
</mailSettings>
</system.net>
I've tried these settings, and also tried explicitly setting the properties of my SmtpClient object @ run-time. On send, I receive the following exception
"Failure sending mail. Unable to connect to the remote server - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 64.202.165.58:25"

I can find loads of posts about codes to send emails using smtp, but I've got a problem. I want to send a registration mail to a user that has made a new account on my site, so he can activate it by clicking on a link in the mail. Only problem is: I need to use an smtpserver but I don't know which smtpserver i can use, so the mail is never sent!

I have this web application (LAN) that sends an email when users registers to one of our events.
The code is pretty straightforward:
[code]....
The application sends the email without problems. The issue is that somehow a third person is enlisted in the cc, and receives a copy of the email!. What could be the problem? The smtp? IIS?

TL;DR - Any webapp devs out there able to squeeze performance out of using gmail as SMTP server without a 3-10 minute delay to delivery?I'm looking for some feedback from developers who are using gmail as a secure SMTP server for use with Webapps.Within the past 2 weeks, my company has switched to gmail to host email for our domains.I have a few webapps that send from our ISP server, but I'd like to refactor the code to use gmail with our domain name. I know the ISP can rig things up, but I don't want relay issues.I have gmail sending for the Webapps and it's more or less working. On ASP/IIS, I'm using SSL and on PHP Linux, I'm using TLS.It seems that TLS (port 587) works better than plain old SSL (port 465), but the overall performance difference seems minimal.What concerns me is that there is often a significant delay (10-20 minutes at times) to get email to a recipient no matter which method I use to send via gmail.While I understand this can happen in any environment, I am used to fast delivery. Use case is salespeople talking to customers and needing to get email to them very quickly using the Webapp. Before the gmail switch, usually less than a minute to deliver. Now, it is 3-4 minutes minimum.Am I crazy to try to use gmail for this purpose? There seem to be a lot of devs using it, so just wanting to know how it works out for them/you.

I'm experiencing a to me mysterious error when sending e-mails through a SMTP-server from an ASP.NET web application. I get the famous error "unable to relay for xxx@yyy.zzz". What's mysterious to me is that when I cut and paste the exact same code that sends the e-mail into an usual .NET Windows Forms application, send the e-mail with this application, it all works just fine. This made me think that perhaps the problem is that the ASP.NET application runs as NETWORK SERVICE while the Windows Forms application runs on a domain user account, but it turns out that I have another ASP.NET application sending e-mail through the same SMTP-server running under NETWORK SERVER at the same IIS, and this application does not experience this problem.
I've further tried to send e-mails through the SMTP-server manually by telnet the smtp-server on port 25 and running the SMTP-protocol manually, and it all works fine. The SMTP-server is not configured with any kind of authentication or SSL.
Another mysterious fact is that the ASP.NET application can send e-mails from an adress within the same domain to an e-mail adress within the same domain, but not to any adress outside of the domain. But the Windows Forms application, that uses the exact same code, can send e-mails from any adress to any adress both within AND outside of the domain.
So to summarize:
The ASP.NET application can send
e-mails from addresses within the
domain to adresses within the domain,
but not to addresses outside of the
domain.
A Windows Forms application running
the same code on the same computer
can send e-mails from ANY address to
ANY address.
Another ASP.NET application on the
same IIS running under the same
account (NETWORK SERVICE) can send
e-mails using the same SMTP-server
from ANY adress to ANY adress.
There is no authentication configured
on the SMTP-Server.
Both the ASP.NET application and the
Windows Forms application utilizes
the System.Net.Mail.SmtpClient class
to send a
System.Net.Mail.MailMessage.
The code that sends the e-mail massage is:
private void button1_Click(object sender, EventArgs e)
{
MailMessage mesasge = new MailMessage(txtFrom.Text, txtTo.Text, "Test mail", txtBody.Text);
SmtpClient client = new SmtpClient();
if (!(string.IsNullOrEmpty(txtUserName.Text))) //Is false since txtUserName.Text is empty
client.Credentials = new System.Net.NetworkCredential(txtUserName.Text, txtPassword.Text);
client.EnableSsl = false;
client.Host = txtServer.Text;
client.Port = 25;
try
{
client.Send(mesasge);
}
catch (Exception ex)
{
txtResponse.Text = ex.Message;
}
}
As far as I can understand, this should be a matter of configuration rather than coding issues.

I know I'm missing something. I'm getting this error when trying to use the script below it. The data I need comes up fine but I don't know how to get it into a loop that works for Bcc. Ideas? If a hard code a single address into bcc it works fine. If I append the body with the datatable records to see if the data is actually there, all the data expected is there.Unable to read data from the transport connection: net_io_connectionclosed.Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.Exception Details: System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed.

I have developed a colleg web applicaition. I have used my gmail account as my smtp server to send back to the client passwords from "Password recovery" link. The problem is that , I am able to send messages only from my gmail account. I want to know whether I can send messages using different e-mail addresses of the clients retrieved from the database instead of sending the mail using my own.

have code on a web form -- when you hit the button "send emails", it executes this sub which reads an SQL database table and sends emails one by one -- however I get this error above -- anyway to check it and skip to the next email? Some emails in my table have name@test.co.il for example, so it seems this causes this error.
