Two possible ways:

a) Just write a script to find identical mails and replace them with
hard links to the same file. :)

b) Use deliver -p <file> for delivering mails. You'll probably need to
write some kind of a script for delivering mails, so that when it gets
called with multiple recipients it can write the mail to a temp file and
call deliver -p for each recipient using the same file.

So yeah, either one are as reliable as the script :)
