in thread Trouble emailing zip file

When using the LIST form of system() the first argument is the program to run, the rest of the arguments are the parameters for the program. I can almost guarantee you don't have a program called /usr/bin/mailx uuencode $zipfile $zipfile -r -s on your system. You probably have /usr/bin/mailx however. The other parts (uuencode $zipfile $zipfile -r -s) need to be passed as parameters to mailx.
my @emailcmd = ('/usr/bin/mailx', 'uuencode', $zipfile, $zipfile, '-r' +, '-s'); #and later my @args = (@emailcmd, $subject, $recipient); system(@args) == 0 or die "system @args failed: $?";

This is of course assuming that the command /usr/bin/mailx uuencode file.zip file.zip -r -s Subject Recipient indeed works on the command line.
