You should have seen my inbox while I was testing. Just to be safe I re-routed everybody’s notifications to myself until I was sure it was working, and yes, I was flooded.
I’m not declaring it officially ready yet. There are still some kinks to work out in my sorry excuse for “code”, and additionally the sudden surge of outgoing messages has triggered our hosting provider’s automated outgoing mail threshold (which is normally a good thing since it usually happens when people’s servers get compromised). So I’m waiting for them to reply to my request to manually raise the limit.
I think the option to disable mail notifications should work now. But please note that the old option no longer exists, and you will have to disable it again if you don’t want to receive any email notifications for subscribed threads…
Went back to see exactly what I did. Account, edit, subscriptions, checked do not send email notifications. While I was there I tried again and it worked without the error message. Think it’s now fixed, thanks SB.
