I have a spam-problem like anyone else. Most of the spam my listserver receives has some kind of impilict destination so the implicit rule catches most of the spam that way. This is fine. What is not so fine, however, is that this results in a moderation message to the sender. I'd like to stop that so that the spammer has no confirmation that the mail was received.
That is not the issue. Sending the held message notice to a spammer, if it reaches the spammer, is probably inconsequential. The issue is that virtually always in spam the sender address is either undeliverable or is the address of an innocent 3rd party. Sending these notices to innocent 3rd parties is called backscatter and is a bad thing.
To avoid this backscatter, you can set the list's respond_to_post_requests attribute to False. There are two problems here. One is this setting is not currently exposed in Postorius, and the other is this will also stop desired held message notices such as those from list members.
