Asp - SmtpClient.Send Exception - Unable To Connect To Remote Server
Mar 6, 2011
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 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 have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.
But, problem is when I try this code from my work place, it does not work. Shows error:
"unable to connect to the remote server"
From a different machine in the same network:
"A socket operation was attempted to an unreachable network 209.xxx.xx.52:25"
I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].
Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.
note that, the code was tested from development environment, visual studio 2005 and 2008.
try
{
MailMessage mail_message = new MailMessage("xxxxx@y7mail.com", txtToEmail.Text, txtSubject.Text, txtBody.Text);
SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com");
NetworkCredential Authentic = new NetworkCredential("xxxxx@y7mail.com", "xxxxx");
mail_client.UseDefaultCredentials = true;......

I have got this error
Unable to connect to the remote server
when I call the web service from the windows service. But I can visit this web service through IE and I also wrote another console application to call the web service and it works fine, too.
The exception infomation is below:
A socket operation was attempted to an unreachable network 127.0.0.1:8888
Here is my code:
WebImageSVC webSvc = new WebImageSVC();
ConfigManager.LoadConfigManager();
webSvc.Url = ConfigManager.WebSvcAddress;
webSvc.Proxy = null;
webSvc.CanUpload(0, "");
I try many methods, like turn off the firewall and anti-virus software, set the web services proxy property to null. but still cannot solve this issue.

I give following connectionstrings.

2. <add name="DatabaseConnectionString" connectionString="Data Source=nt1111;Initial Catalog=testdatabase; User ID=test;Password= "***"; User Instance=False" providerName="System.Data.SqlClient" />
3. The same as 2 but with IP <add name="DatabaseConnectionString" connectionString="Data Source=999.99.9.99;Initial Catalog=testdatabase; User ID=test;Password= "***"; User Instance=False" providerName="System.Data.SqlClient" />

I'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?

I have 2 servers. the database server (DB1) which has sqlserver installed and the application server (WEB1) which has my web application. They are both on the same network and both have the same administrator login.
My web application on the application server needs to access the database on the database server. sqlserver is set to mixed mode in security. i created a random sqlserver user login that can only access my database and set it as the db owner. I use the username and password for this in my connection string. when i run my web application i can read information but i cant write to the database. My app is using windows thentication. I have set my NT AUTHORITYNETWORK SERVICE account to db_owner for my database as well... grabbing at straws!
Question 1: When my application talks to sqlserver does it use the administrator login or the NT AUTHORITYNETWORK SERVICE account which i got from using windowsidentity.getcurrent()?
Question 2: If I use ASP.Net impersonation, what does this do exactly? Because if i run the ndowsIdentity.GetCurrent() i get the username that i specified. How does this tie in with my connection string?
Question 3: If I dont use impersonation what and how do i have to configure sqlserver to accept my insert/update requests? Do i need to work with the NT AUTHORITYNETWORK SERVICE? or can i just use my user login? What do i need to add or remove from my connection string? (see below).

I have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local database. So, how do I get the Server Explorer to connect with a remote SQL Server database?

I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:

We have a database on our server, here at the office. We now want to create a asp.net website that will be accessible to the public.
Say the domain of the website is [URL] and it's hosted on a webserver of HeartInternet.
When someone connects to that domain, that webpage must be able to pull data from our server that is located here in our office.
In other words the webpage cannot just load data out of the MySQL database loaded on its server, but it has to connect to our server and get data.

I'm not sure why but on random occassions after I have added an update to my site via ftp and then try to access the site through the browser I get an "out of memory" exception. But there are no infinite loops or problems like that. Then after some time it will then work (I assume the web hosts restart IIS or something) and all is fine again. Server Error in '/' Application. Exception of type 'System.OutOfMemoryException' was thrown. 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.
