Kind of along the mail/script lines:

Is there a way to send a mail message to a bunch of people who's mail
addresses are maintained in a file?

Thought of a shell or perl script that would open the file and, for each
iteration of a loop, assign the line content to a variable and issue a mail
command, putting their address in the destination field.  Then assign the
next line (address) to the variable and loop again, until EOF.
