I rebooted my server this evening as I was doing some work on it. After that, I just got an email notification from my BellaOnline forum that one of my editors responded to one of my posts. It definitely is a message about the post I made and her response to it. It's with a nice fresh rebooted server. She posted after the reboot so it wasn't a historic message.
I then ran:
select user_real_email from ubbt7_user_profile where user_email_watchlists <> 0;
It came back with zero rows.
I checked the database for my member record and user_email_watchlists is definitely 0 as in zero.
Any other thoughts why I received that email message? It wasn't with the forum's main account. It was with a separate account I use for posting. It wasn't in a forum that I moderate personally.
