Ok, all you guys rock for all of the help. I changed;

my $mail = "@_";
[download]

to

my $mail = @_[0];
[download]

This seems to work because I actually have a foreach loop in the main. It is getting past the open but not the close on the filehandle. I basically get the same message: Cannot close C:/windows/desktop/ tmp/test.f2mail,Bad file descriptor. Where ever there is confusion to be had... I'll be there.
