Now that email confirmations have been enabled, there has been a fair amount of traffic to the OTRS resulting from people replying to the confirmation email they receive instead of clicking on the link in it.
The From: address of the confirmations is wiki@wikimedia.org, an address which is being redirected to the info-en OTRS queue.
There is nothing we at OTRS can do to help these people.
I would like to suggest that perhaps another From: address be used, ideally one that produces an automatic bounce.
