Saving an email as .eml with Windows Service

Question

I have a service that is used to automate an e-mail system, it also saves a copy of the .eml file in a local folder.

Using the Outlook Interop dll works fine for interactive applications, however we need to make it a service, which is non-interactive, and making the service interactive would render a lot of security issues.

tl;dr Is there any way to save the .eml file in a folder using a non-interactive Windows Service?

PS: The e-mail is a System.Net.Mail.MailMessage object.

I just did a google search and tons of results came back .. have you tried doing one yourself..? this has been done before successfully btw — MethodMan, Feb 12 '16 at 18:36

Unfortunatelly I already tried that solution, none of the alternatives support the .eml extension. — Lucas, Feb 12 '16 at 18:44

System.Net.Mail.SmtpClient contains built in functionality to write the message to disk in .eml format:

using (var c = new System.Net.Mail.SmtpClient.SmtpClient()
{
    DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory,
    PickupDirectoryLocation = "c:\\temp"
})
{
    var mail = new MailMessage("someone@example.com", "someonelse@example.com", "Very important", "No, just kidding");
    c.Send(mail);
}
