You can do both of these with routers that defer the messages if
certain conditions are met, for example they are to specific addresses
and it's within a certain time. The one thing you should be very careful
about is message timeouts and retry timing; you don't want a message to
expire while you're defering it this way.
Writing out the specific conditions you need will take some exploring
in the Exim documentation about string expansions, ${if} conditions, and
so on. Alternately you can do the brute force solution: simply have a
file of addresses that are unconditionally deferred, then have a cron
job that puts specific addresses in the file at 17:30 and then removes
them at 07:00 (and probably starts a queue run on the spot).
A general defer-addresses-in-file router is:
defer_any:
debug_print = "R: defer_any for $local_part@$domain"
driver = redirect
allow_defer
data = :defer:delivery temporarily stalled.
no_verify
no_expn
condition = ${if match_address{$local_part@$domain}{/etc/exim4/exim-defer-addrs}}
(Note that this deliberately allows wildcards, so that we can for example
list '*@*' to defer *all* email.)
This router should be before any real router that can actually deliver
to things.
