Configure a autoresponder to send a Multipart (HTML and Plaintext) email

When setting up an MDaemon autoresponder it is often nice to be able to respond with formatted text in HTML.  However if this email is received by a client that can only read plain text then the response will show the HTML code and will be difficult to interpret.

The correct approach is to send back a multipart email that contains both a HTML version of the message as well as a Plain text version.
 
The template below can be used in MDaemon to send back a correctly formatted multipart message.

The first section contains hashed comments feel free to edit this as you like.

# Multipart sample auto-responder script
#
# Note: Lines beginning with # are comments
#
# This is an example script that demonstrates how to send
# an autoresponder message using a Multipart mail (HTML and Plain text).

This next section is the text version of the email with the correct content type:

–0304_0930_59_PART-BREAK
Content-Type: text/plain; charset=”us-ascii”

The body of the email in plain text:

simple HTML bold

This next line defines the end of this Mulitipart section

–0304_0930_59_PART-BREAK

This next section is the HTML version of the email with the correct content type:

Content-Type: text/html; charset=”us-ascii”

The body of the email in HTML:

<HTML>
<div><font style=”font-family: tahoma; font-size: 10pt;”>
<div><br />
&nbsp;simple HTML <strong>bold</strong></div>
</font></div>
</HTML>

This next line defines the end of this Mulitipart section:

–0304_0930_59_PART-BREAK–

The following two lines set the subject header to RE:(the original subject), and the message content type to Multipart:

%SetSubject%=RE: $SUBJECT$
%SetContentType%=multipart/alternative; boundary=”0304_0930_59_PART-BREAK”


In this example I used the part break value  0304_0930_59_PART-BREAK this is actually made up from the date and time of when the message was sent  “Month,day_Hour,Min_sec_PART-BREAK”.

This value has to be unique per message so it’s not a problem if you keep it as the example, or if you prefer you can change this to any valid date and time.
