Is there a hook into the mailing list mode that could allow us to suppress emailing certain posts, say posts from a certain user? Could it conceivably be done with a plugin?
We have a plugin that auto-inserts a wiki post, as the first post in a topic, whenever a topic is created. The wiki post is just a template and has no value when it is first created- it will only gain value over time. But creating the wiki post triggers a nuisance email for those who have mailing list enabled. Half of our group uses mailing list mode. (That’s unusually high, I know, but we’re coming from a Google Groups background, so there’s some inertia.)
The wiki posts are automatically posted by a fictitious user named “Summary”, so that’s the most obvious criteria to filter on.
