question on batch email sending

[David Banning]

I have a standard mailbox with around 40 messages. I want to be able
to just send them all to someone, the same person, not as an
attachment but as individual emails. I want to do something like;

cat /var/mail/frank | someprogram franksnewaddress at franksdomain.com

So that Frank can just get it into his regular inbox. I realize that 
I could just ask Frank to pop it off the server but then he would have
to setup for just one occasion. Is there a way to do what I want?
