two ideas, one bad and one less bad, certainly not new:

1) can we have a message_multi, or whatever, similar in action to
log_message, immediately writing a multiline (5XX- ) response to the
smtp stream?

So:

deny/defer/accept .... [determines is 5/4/2XX message]
conditions/actions [excluding a message_multi]
conditions/actions
...
actions [delay/log_message/message_multi]
message_multi .....
...
repeat... [but no more conditions]
message ... [not necessarily last, but it would define the last response]

conditions have to be before the first message_multi, because before
sending a response to the smtp stream we must be sure that the verb
(deny/warn/accept) has succeeded. This would enable an easy on-line
tarpitting:

ex:

deny    message = you have been tangoed!
    condition = [check helo]
    condition = [check sender domain]
    delay = 10s
    message_multi = wait a second
    delay = 10s
    message_multi = the coffee is not ready yet
    delay = 10s
    message_multi = tanto va la gatta al lardo...
    delay = 10s
    message_multi = ...che ci rimette lo zampino
    delay = 10s
    message_multi = knock knock
    delay = 10s
    message_multi = who is there?
    delay = 30s
    message_multi = you've got the idea...



under the "warn" verb message_multi would have no effect.

2) much simpler would be a delay_multi condition (always return
true), that would introduce a delay for each newline in a multiline
response. So, for instance:

deny    message = first line\nsecond line\nI got bored\nfourth line
    condition = ....
    delay_multi [position is unimportant]
    condition = ...
