How Can I Save .NET MailMessage Objects as .eml or .msg Files?

Exporting .NET MailMessage Objects to .eml or .msg Files

The .NET MailMessage class lacks a built-in function to directly save email data to disk. However, we can achieve this using alternative methods.

Leveraging SmtpClient and a Designated Pickup Directory

The SmtpClient class offers a solution: directing email messages to a local directory instead of a remote server. This is accomplished by configuring the SmtpClient as follows:

<code class="language-csharp">SmtpClient client = new SmtpClient("mysmtphost"); // Or use an empty constructor for local saving
client.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
client.PickupDirectoryLocation = @"C:\somedirectory";
client.Send(message);</code>

Alternatively, this setting can be defined within the application's configuration file:

<code class="language-xml"><configuration>
  <system.net>
    <mailSettings>
      <smtp deliveryMethod="SpecifiedPickupDirectory">
        <specifiedPickupDirectory pickupDirectoryLocation="C:\somedirectory"/>
      </smtp>
    </mailSettings>
  </system.net>
</configuration></code>

Following the Send command, the generated email files will reside in the designated directory.

Important Note: For local file creation, an empty constructor for SmtpClient can simplify the process, as network transmission isn't required.
