I haven't tried it but I spotted this earlier. I suppose you could use
it at the first stage of your ACLs
http://www.exim.org/exim-html-4.30/doc/html/spec_38.html#CHAP38
delay = <time>
This modifier causes Exim to wait for the time interval before
proceeding. The time is given in the usual Exim notation. This modifier
may appear in any ACL. The delay happens as soon as the modifier is
processed. Like control, delay can be used with accept or deny, for
example:
deny ...some conditions...
delay = 30s
The delay happens if all the conditions are true, before the statement
returns "deny". Compare this with:
deny delay = 30s
...some conditions...
which waits for 30s before processing the conditions. The delay modifier
can also be used with warn and together with control:
warn ...some conditions...
delay = 2m
control = freeze
accept ...
