Comment got through, yes. And I think comment notification emails aren't getting through because my webmail provider decided to blacklist LJ's servers. Annoying, but not the first time. When that happens, email gets bounced at the gateway, so I don't even see it in my spam folder or get the chance to whitelist it. I never even find out that a message was sent. But it's something just about every email provider I know does, without telling you they're doing it.
