I am just at a loss for a better way to do this within my limited environment.  I do run sendmail on this box, but I am not sure if it can dump attachments without some additional piece of software.  I saw a very nice bit of Perl code in my Googling before asking here, but it required a Perl MIME module that Redhat does not distribute with RHEL.

I said to heck with the restrictions and installed the required CPAN modules.  Everything is working perfectly.
