Definitely so. This list is a living example.

If you don't mind letting Exim have read-access to the lists, you can make
Exim+Ecartis reject *during* smtp session. Ergo can probably do the same just as
easily with Mailman.

That said, experiments aside, I don't bother - just silently blackhole Ecartis
post-smtp response to those and use an errors_to = /dev/null on the routers.

The admins still see the reports, so 'good enough' to catch honest errors, less
work, and lower risk of backscatter.

Not much point in respecting RFC sensitivity with a zombot.
