If you use the C-shell you could try the following command 

set mail = ( 10 /usr/mail/$LOGNAME certain_directory )

csh will then send you the message
"New mail in certain_directory"
whenever a file is added or removed from that directory.
You can use ls -t or whatever to find the actual name of the file.
