Have you considered doing something insane like using the "queue_only"
control and then simply not running a queue runner? Instead use a script
that is run once a minute to scan the exim mail queue (exim -bp) and
only deliver messages (exim -M <message-id>) if they're over 10m old?
So long you don't have a huge mail queue it might work. Never tried it,
but it might give you that 10m buffer or whatever buffer you want
without having to deal with retry rules.
It has some issues .. you would have to implement your own retry db for
all the message that didn't make it on the first queue run to stop it
from trying to send the message every minute thereafter :P Hmm... maybe
retry rules are the way to go there too as exim wont actually attempt a
delivery after the first one until it's up for a real retry as per the
rules.
I really shouldn't post first thing in the morning .. too many weird ideas.
