I can specify a port number with SmtpClient object in ASP.NET, what I am wondering is, is that just the port .NET uses to send mail to the SMTP server? Or will that dictate what port for the SMTP server to use? Or is it that it MUST match the port configured for the SMTP server?

Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008
CSS sample:
body
{
height:1200px;
width:920px;
border-style:solid;
border-color:blue;
padding:10px 10px 10px 10px;
}
#toptext1
{
position:relative;
top:-225px;
right:-500px;
font-size:22px;
font-weight:bold;
}
From the master page:
<body>
<form id="form1" runat="server">
<asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server"
AlternateText="CookNook" Width="449px"></asp:image>
<p>
<asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label>
</p>
From the content page:
<%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" />
</asp:Content>
When I was doing this without a master page it worked so where am I going wrong with the attributes?
When using the system.net/mail web.config settings to configure my SmtpClient, it fails to deliver emails, with an "protocol error" described best by Base64 encoding and authentication problems:
Example:
With the following Config
<system.net>
<mailSettings>
<smtp from="[URL]">
<network host="[URL]"
port="2525"
defaultCredentials="false"
userName="username"
password="password"/>
</smtp>
</mailSettings>
</system.net>
And the Code:
var tmp = new SmtpClient();
MailMessage msg = new MailMessage();
msg.Subject = "test";
msg.From = new MailAddress("[URL]");
msg.To.Add(new MailAddress("[URL]"));
msg.Body = "test";
tmp.Send(msg);
Produces the error message:
System.Net.Mail.SmtpException: The server committed a protocol violation The server response was: UGFzc3dvcmQ6
at System.Net.Mail.MailCommand.CheckResponse(SmtpStatusCode statusCode, String response)
at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException
& exception)
at System.Net.Mail.SmtpClient.Send(MailMessage message)
However, in the following code where I manually set all the properties, the code runs without exception and the email is delivered.
var tmp2 = new SmtpClient("[URL]", 2525);
tmp2.Credentials = new NetworkCredential("username", "password");
tmp2.UseDefaultCredentials = false;
MailMessage msg = new MailMessage();
msg.Subject = "test";
msg.From = new MailAddress("[URL]");
msg.To.Add(new MailAddress("[URL]"));
msg.Body = "test";
tmp2.Send(msg);
i've encountered some problems sending an email to disignated email address that i passed in.
they gave me this error
[Code]....
what does the Parameter name: address means??
I am having some problems sending emails (using gmail). I have an application that allows a user to send an email, request info, etc. I want the email "from" address to be from the initiating user. I set up the settings in the web.config for the first time. Previously, I had always set up the info directly in the code. The email is sending just fine. However, the from address shows the user name correctly but the email address in the one in the web.config.ie. "User From Name <web.config from address>". In the code, the MailMessage object shows it correctly ("User From Name <User from address>"), and the SMTPClient From address shows the web.config from address. This is going to be confusing for the recipient of the emails to see the config address with the user name.
I tried removing the From address from the config(leaving the required userIDpw for the email logon, but no difference. I also tried removing the config mail settings completely and putting it back in the code. Still no luck.
How can I get the from address to be the valid email address in resulting email?
How do I format the body of the email so it doesn't look so old school :) I've tried sending html through it, but it just comes out as html in the body of the email.
View 2 RepliesI am trying to send attachment mails in asp.net pages using SmtpClient Send() method.
It is working fine with 2mb files. When i tried with 7mb attachment file, it is saying:
"Failure sending mail."
What is the max size for sending mail using SmtpClient.Send(message) method.
Why the above error coming.....?
I am working on a project where one of the requirements is to re-write an ASP.NET application. The old ASP.NET application was based on .NET Framework 1.1. The new ASP.NET application is based on .NET Framework 3.5.
One of the functions in the old web application was the ability to send email. The old code used the System.Web.Mail.SmtpMail class, whereas the new web application uses the System.Net.Mail.SmtpClient class.
In testing this on our development servers, everything worked fine. However, we have two beta clients testing out our software, and they both run into problems sending email in the new web application.
The specific exception is as follows:
"Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it"
Both the old and new ASP.NET application are on the same server (Windows Server 2003). They both are using the same Exchange mail server. Why is it that the old ASP.NET application can successfully send email, but the new one cannot?
I looked at the old code, and it did not use any form of authentication, it just specified the sender's email address, the recipient's email address, the subject, body, and server, and sent the message. I did the same thing in the new code, with the only difference being that I used the SmtpClient class.
Below is a code snippet from the new ASP.NET application:
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
mail.To.Add(messageTo);
mail.From = new MailAddress(messageFrom);
mail.Subject = messageSubject;
mail.Body = messageBody;
SmtpClient client = new SmtpClient();
client.Host = smtpServer;
client.Send(mail);
I am trying to use System.Net.Mail SMTPClient to send emails. I have the sample code from MSDN:
[Code]....
What is the host name? I want to send emails using Exchange Online which I think the host is "red001.mail.microsoftonline.com"?
i am trying to send email using simple SMTPClient class, as the following code:
[Code]....
when i put the To email to be an Gmail,yahoo, hotmail email "as in example" or another domain.com email, the code is working with no issue, but when i put the recepient email to be any of Google Apps Emails, unfortunately the email didnot received. does the SmtpClient have a problem with google apps?
I use SmtpClient to send email. I want to ensure that the SMTP connection gets closed after each message is sent. I found an explanation of how to do this in the SmtpClient documentation on MSDN:
[URL]
One thing it says is: Call Dispose when you are finished using the SmtpClient. The Dispose method leaves the SmtpClient in an unusable state. After calling Dispose, you must release all references to the SmtpClient so the garbage collector can reclaim the memory that the
SmtpClient was occupying.
I have a question about the last part. What exactly does "release all references" mean. How do I do that?
I'm running a website and to keep my members informed I regularly send mails to our members by the following code :
[Code]....
But the problem is that some mails are not been delivered when I do this by this code.
This is especially not done for gmx.de or gmx.eu mails; but also for other type of mail addresses.
When I send the mail individually I don't have problems.

My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details:
Exception: Failure sending mail.
Inner Exception: Unable to connect to the remote server
Inner Exception(2): 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 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient()
smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net"
smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?

I run a Exchange 2010 server and created an account for one of my websites to send e-mails.
The webserver's IP is even listed on the [Organization Configuration] -> [Hub Transport] -> [Global Settings] -> [Transport Settings] -> [Message Delivery] list.
The code sets a set of Network Credentials, but setting incorrect or correct settings, it doesn't matter; if I list external e-mail addresses, I get a "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for <address>" message, 'local' addresses that are cc-ed, do get delivered...
When checking with telnet, I noticed that the only AUTH option was AUTH NTLM, but when checking the NetworkCredentails, it stated that NTLM should would.
ASP.NET 2.0 and COM Port Communication
I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service.Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique.
I need a sniffer to catch all http communications on certain port, recommend one for me.

EDIT:
I use the web development server that ships with Visual Studio... If go to Control Panel -> Phones & Modems -> Modems i could see my mobile connected in com6.. i have tested the winform application it works fine.Is this the answer? ASP.NET pages are supposed to work.What is happening over here is that when you click on open_com button, the ASP.NET page posts back to itself, executes the event handler i.e., opensthe port. Then when the page finishesprocessing the post back, it is unloaded. At this point the COM1 objects is also destroyed.

View 6 RepliesI'm needing to send around 500-2500 emails out at a time to internal email accounts. I'm wondering which was would be faster both for the mail server and for my client app. Should I send multiple emails with just different TO addresses, or just one with multiple BCC addresses? I tried testing this by sending a bunch to my own email and the multiple emails method work, but with the BCC and a single message I only get that single message in my inbox. Shouldn't I be getting as many copies as the number of times I put my address in the BCC line?
