You'd need a script to create the proper header, like:

MIME-Version: 1.0
Content-Type: multipart/alternative;
types="text/plain,text/html";
boundary="------------E625F5AD6F957318951A113A"


Then the "boundary headers" (seperating the attachments)

(this one is just below the headers, at the top of the
body)

--------------E625F5AD6F957318951A113A
Content-Type: text/plain; charset=iso-8859-1
Content-Transfer-Encoding: 8bit

<plain text document here>


--------------E625F5AD6F957318951A113A
Content-Type: text/html; charset=us-ascii
Content-Transfer-Encoding: 7bit

<html document here>

--------------E625F5AD6F957318951A113A--


There are different kinds of headers, depending on the types of
document. Those long character strings that look random, are.
So you'll need to be able to generate random strings, which
shouldn't be a problem. Md5sum run on the file itself would work
fine.

$ md5sum random_file

c9c7409dded45c022a167833ed8663e6 random_file

The script would then need to run the file through mimencode (or
a similar utility) and insert it between the correct boundaries.

It's not something I've done, so I should turn you over to an
expert:

Seems like you could probably use a single set of headers with
detail variations, but I don't know for sure. That would make
the script a lot simpler.

I wouldn't use uuencode except to someone you know who uses a
compatible version. There is some variation. And I don't think
windoze weenies or big macs use it.

Mimencode is the way to go for business and the general public.
