system.net.mail

Is there anyway to have all emails go to a different address when System.Web.HttpContext.Current.IsDebuggingEnabled is true? Or do I need a new class which I use to send email everywhere? We use a similar solution to the MailProxy method detailed by tvanfosson. However we have a few differences that I feel are worth mentioning. The first is that we simply extend the SmtpClient class and override the Send methods when in a development or testing environment. We use a config file to determine the environment. We then use this class anytime we need to send out emails. This class will determine

Searching StackOverflow, I found this question on how to Retrieve SMTP settings from Web.Config , but no details on how to update the SMTP back to the web.config file. I started with the following code: Configuration webConfig = WebConfigurationManager.OpenWebConfiguration("~"); MailSettingsSectionGroup settings = (MailSettingsSectionGroup)webConfig.GetSectionGroup("system.net/mailSettings"); SmtpSection smtp = settings.Smtp; SmtpNetworkElement net = smtp.Network; but was quickly clued in by Intellisense that SmptSection.Network is a Get (aka "read-only") accessor. So how am I supposed to

I have a problem creating application to send email. I already have one working as a Windows Forms Application and then decided to do the same from the empty project, because I need to make a background application now. I used the System.Net.Mail namespace for that in a Windows Forms. Then added the same code to the new project. However, I get the following error: The type or namespace name 'Mail' does not exist in the namespace 'System.Net'. The 'System.Net' reference is included in the project references list and I can't find anything named 'System.Net.Mail' in the list of possible

I have trouble creating a simple mock mail sender within an ASP NET 5 project. Here the method : public static Task SendMail(string Email, string Subject, string Body) { SmtpClient client = new SmtpClient(); client.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory; client.PickupDirectoryLocation = "C:\\TMP"; MailAddress from = new MailAddress("jane@contoso.com", "Jane " + (char)0xD8 + " Clayton", System.Text.Encoding.UTF8); MailAddress to = new MailAddress(Email); MailMessage message = new MailMessage(from, to); message.Body = Body; message.BodyEncoding = System.Text.Encoding.UTF8;

I just noticed that some of the email operations in my code have been failing and am trying to fix it up, however I keep getting the following error: System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[]

I'm trying to write a notification service (for completely legit non-spam purposes) in .NET using SmtpClient. Initially I just looped through each message and sent it, however this is slow and I would like to improve the speed. So, I switched to using 'SendAsync', but now get the following error on the second call: An asynchronous call is already in progress. I read this to mean that MS crippled System.Net.Mail to prevent mass-mailers. Is this correct? If so, is there a better way to do this in .NET, and still be able to log the results of each email(which is important to our client). If not,
