I'm trying to work out a mail system which can send an attachment as well
as an HTML formatted message (and a default plain text version).
I found some pretty good code on PHP.net and modified it a little but I
can't seem to get it to work.
It attaches the file properly, but only displays the Plain Text message,
even in an HTML-capable mail client.
I'm guessing it has something to do with the placement of the boundaries,
but I can't figure it out.
TIA
