MIME::Lite Problem

[Phil White]

Hello.

This is an appalling plea for a little help. My sincere apologies, but
I have been bashing my head against this for a week now, and my
ignorance is driving me crazy...

I am trying to amend an existing program that uses MIME::Lite (because
it is both efficient, and is well written).

The email to be sent is first created in full, then, once complete, is
passed to a small subroutine for sending. To this end, the email
message if stored in an anonymous hash.

A summary of the code is given below. What I need to be able to do, is
create a new multipart container, and attach this to the aforementioned
anonymous hash - it is this part that I am failing on...

If you have any ideas on how I might solve my conundrum, I'd be very
grateful. 

Best wishes,

Phil.
