Part of managing your own infrastructure is making mistakes about things like email services, etc. Knowing your limits is critical. I didn't. Ha!
So here's what happened -- when I set up my blog system, I started using isso because I didn't want Disqus owning my data. I also had my own email server on my Synology NAS. However, when I replaced my Synology NAS with a Drobo, I never set up a new email server. So, any blog comments that folks have written, I didn't get notified about.
Today I remedied that by pointing isso at gmail. Long-term, this will not be workable, as I eventually don't want to be relying on gmail for such things. However, that's where I am today.
Apologies to those whose comments didn't get moderated in a timely manner!comments
