[Exim] batch emails

I have a question. This may be a FAQ, and I'm sorry if it is.

My system is relaying a LOT of mail to a particular address. I was
wondering if there was a way I could configure exim to only send mail to
user@??? between the hours of X and Y? If mail is recieved for
that user before that time, it is held in the Queue till it's time.
