Our mail server appears to be working normally. Do you have your control panel set to receive instant notifications and are you definitely subscribed to threads that have received replies since your last visit?
Yes, I am subscribed to all thread and it clearly shows in my control panel.
I've double checked options in control panel but to no help. This problem is there for pretty long time now. Earlier I thought it's some temporary problem with the server and will be resolved with time automatically.
But the problem persists. Try looking at my setting in control panel...maybe I am doing something very stupid.
