13.  Parse Header

Description:

Parses email header to determine sender, recipient, and other important information.  This is the mode that WindMail is most often used in.  This is also the most secure mode in which to use WindMail.  Using the Parse Header feature allows you to specify user-defined data without the risk of users executing applications on your server.  Another key reason to use the Parse Header function is that thousands of programs written for Unix already call Sendmail this way. It is only a matter of changing that call to WindMail instead of Sendmail (which isn’t included with Windows NT) in order to port many of those programs to a Windows environment.

Usage:

windmail -t

Format:

Every email message has a simple header.  The header simply contains some information that tells you where the message came from, who it is going to, and the Subject and Date of the message.  The format is fairly simple:

From: user@testdomain.com

To: anotheruser@testdomain.com

CC: someone@testdomain.com

BCC: boss@testdomain.com

Subject: The subject of the message

After the header of the message there is a blank line before any of the message text begins.  There are only a few header lines that are significant.

Notes:

Significant Header Lines for Parsing:

From: Email Address the message is supposed to be sent from

To: Primary Address(es) the message is sent to

CC: Carbon Copy Address(es)

BCC: Blind Carbon Copy Address(es)  *do not show up in final mail

Subject: Subject of the message

You can specify multiple To:, CC:, or BCC: lines or you can specify multiple Addresses on one line separated by a Comma or a Semicolon.  You can leave out CC:, BCC:, and Subject: lines…but it is usually good practice to have a From: line and at least one To: line.
