How to write email on disk instead of sending to real address in asp.net?

Question

How to write email (.eml file) on disk instead of sending to real address in asp.net? Thanks in advance.

Answer 1

using (var client = new SmtpClient("somehost"))
{
    client.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
    client.PickupDirectoryLocation = @"C:\somedirectory";
    client.Send(message);
}

or using the config file:

<configuration>
  <system.net>
    <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="C:\somedirectory" />
      </smtp>
    </mailSettings>
  </system.net>
</configuration>

Answer 2

You can configure the SmtpClient to put emails into a configured directory instead of sending them. To do this, you need to set the DeliveryMethod to SpecifiedPickupDirectory and set the PickupDirectoryLocation:

<system.net>
    <mailSettings>
        <smtp deliveryMethod="SpecifiedPickupDirectory">
            <specifiedPickupDirectory pickupDirectoryLocation="C:\emails" />
        </smtp>
    </mailSettings>
</system.net>

When you send emails using the standard SmtpClient, they will now get saved to the specified directory instead of actually being sent.
