Yes, I think so.

The place to hook this in would be in the CommandRunner
src/mailman/runners/command.py

If you look down near the bottom of _dispose(), you'll see where the reply is
created from a UserNotification(), then at the very bottom, it's sent.  The
hypothetical flag controlling this would just skip all that to prevent the
results from being sent.

The question is how controllable would this need to be?  Presumably, the
IMailingList itself would have a flag turning this off,
e.g. `send_command_results`.

If you do end up taking a crack at this, please open a bug and attach a
branch.  Ideally, it would have a unittest or doctest, and it will have to go
through a schema migration, but I can help with that.

This will also take some more elaborate processing in the eml_confirm.py
command.  I think there are enough hints in the confirmation message to know
which mailing list it's coming from, but if not, please submit a separate bug
on this (and a separate branch if you work on a fix).
