With Message-ID header and dovecot lmtp (I think lda works also) you

In my case I have a robot account which sends (from LAN) emails and reports

so all
users who are in both groups get all these messages times two a day.

I have just configured it and it's working great.
if allof (not exists "list-id", duplicate :seconds 7200 )
{
discard;
stop;
}
So in your case you might configure rule that if sender is robot use
Date: or Subject: or other header instead of Message-ID. As it will only
apply to the robot e-mails you don't risk side effects on other e-mail.
Check 3.1 in https://tools.ietf.org/html/rfc7352
Also you can use unique:id somehow with other rules to mark e-mails that
are sent by bot. Let's say that the bot is sending e-mails not more that
once an hour. Than you can deduplicate all e-mails From:
bot and set the timeout to kick in before next time bot sends e-mail.

yes it works great . In my case forcing to add message-ID on messages
that don't carry one, helped to track these messages without any side
effects
(until now of course !)
thanks a lot
