When the first two attached files are used as alternative bodies for the email the file passed with the parameter File to the command Mail will be used to contain human readable headers and a text that will be displayed when the mail client of the recipient does not have MIME enhancements.
Headers listed in the file specified with the parameter File(...) of the command Mail are added to the header of the e-mail.
These are human readable headers like:
Subject: E-mail generated with the Mail command within ITP/Server.
To: "S. Kiddy" <s.kiddy@serverscripts.com>
Reply-to: "Our office" <scriptsRus@itpserver.com>.
There are other headers you could use. See the RFC822 document on the internet (http://www.faqs.org/rfcs/rfc822.html) for a description.
Note: Separate these headers with a blank line from the body.
The body of this file is also sent, but will only be shown if the recipient has an e-mail client that does not support MIME-enhancements. It is customary that this file contains a message informing the recipient that he will need MIME support to read the attachments.
Note
Separate these headers with a blank line from the body.
See the example below for a sample MIME message.
