I dont have the time to write an example in C , but the basic structure
would be to:
1. Extract the list of addresses to mail to.
2. Format the message to include the needed parts ( To: From: Date:
Subject: and message ) etc etc.
3. Use a function that opens/locks ( mail.local have all the neccesary
code to do all this in a function called "deliver" ) that users
mbox-file.
4. Appends the message to the mbox.

As this would not spawn a new process per mail and just appends the mail
directly to the file i think it would be really fast. It would not
necesarily have to be done in C , perl ( or perhaps even some
shellscript ) might do it aswell.

Sorry for not beeing able to help you further but i dont have any time
to spare right now.
