Looks like these, or any 'broadcast' funtionality should really be
(probably already ARE) in a Mailing List Manager.

That toolset should already have a mechanism for controlling delivery
time - or one (such as a 'digest' function) that can be utilized to the
same effect. Sub-lists may be called for.

Using that built-in, or scripting a time-window for it, would probably
be easier and 'safer' than messing with Exim - which one supposes must
continue to be a 24x7 service for all other mail.
