This is entirely possible. You want a router that acts very early on and
looks something like this:

    defer_user:
        driver = redirect
        allow_defer
        data = :defer:delivery temporarily stalled
        no_verify
        no_expn
        condition = ${if match_address{$local_part@$domain}{/etc/exim4/exim-addr-defer}}


Then at the appropriate time, add '*@*' to /etc/exim4/exim-addr-defer
and enjoy absolutely everything being stalled. Because this router is
set to no_verify, it will not stop a RCPT TO address being verified and
thus accepted. (Or even a MAIL FROM address.)
