Because spammer suck, and spam assassin is a product, not a person, comments only get posted after they go through moderation. Of course, that means that I have to know someone’s posted a comment. This used to work great, but when I switched to having mail running on a separate machine, wordpress stopped telling me that a comment has been posted. Until now.
It turns out that a few months ago, no doubt in a moment of “why the fuck is this running?” I turned off the postfix service. Oops. Turned it back on and watched the stream of emails show up in my inbox. Without fail, comment response and moderation time should be a lot better now.
This is why I don’t maintain production systems.
