If you change your script to pass the filename as the msg parameter, and cat the original file to the mail program (rather than echo), you will easily avoid the interpretation which discards the newlines.

That is, the minimal change you asked for would use this

cat $msg | mail -s $subj -c $ccaddr $toaddr -- -f $rtnaddr

Of course, someone will suggest that is a useless use of cat, and note that you could rephrase it as

mail -s $subj -c $ccaddr $toaddr -- -f $rtnaddr < $msg

(which strays a little from minimal -- your choice).
