Considering virutal_alias_maps enable delivery to addresses which aren't users, while this seems like a good security practice, I don't see how it should work to deliver mailman emails to user accounts.
It's not related to delivering posts to subscribers. However, it can be useful for things like trapping undeliverable mail to noreply sources like weblate
I'll not worry about this because weblate only sends emails to user accounts created there, and it seems to work just fine at the moment.
You said that weblate was sending mail to Mailman, and there are conditions under which Mailman would send back. For example, if weblate's mail is being held for moderation, or rejected (vs. discarded, where the mail is sent to /dev/null without notifying the sender).
