You should think in terms of looping through the list of names passed in on the command line. Using $* will expand to all of the names that were given to the script as parameters. If only one name is given, then you'll not see a problem, but when two or more are given things will break if you don't loop and treat them one at a time.
You should also run the command that you're using to search the password file manually from the command line and see what the results are. Do you really want everything that it generates to go into the mail?

continue(1T) Tcl Built-In Commands continue(1T)
__________________________________________________________________________________________________________________________________________________
NAME
continue - Skip to the next iteration of a loop
SYNOPSIS
continue
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code,
which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop
command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as
the catch command and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 10 except 5:
for {set x 0} {$x<10} {incr x} {
if {$x == 5} {
continue
}
puts "x is $x"
}
