Question : HTML in \Inetpub\mailroot\Pickup

I know that I can drop a TXT file into the c:\Inetpub\mailroot\Pickup folder and SMTP will deliver the email message.  The format for these email messages are as follows:

TO: [email protected]
FROM: [email protected]
SUBJECT: Automated message

Place your text here

However, this simply delivers the email in PLAIN TEXT mode.   How does one send an email that is in HTML format?  I would like to be able to drop/create HTML formatted emails, and drop them in the \pickup folder, but I don't know what is required and how it would differ from creating email in PLAIN TEXT mode.

Answer : HTML in \Inetpub\mailroot\Pickup

Add this line:
Content-Type: text/html
