Stop All Mail via Admin permissions.Where Admin Override a users settings.
In other words stop them switching on e-mail notices.
Click Me And the reasoning is that Msn Blocked my servers IP for e-mails,
but if its reported as spam again and i dont take action
then they can block me again.
So all i can think of is to Delete the user if they want to
constantly switch on notifications.
There is Bann
There are warnings
But if i user wants to take the hisss he will.
A tick box to prevent that user turning on / or receive
e-mails at all would give admin piece of mind that there
not receiving, or re-subscribing again.
This seems to be a trend from all the free mail suppliers.And in something IMO needs some serious attention.
