You can filter them out in Gmail by setting up a 'straight to deleted' filter matching on

Drowned in Sound Reset Forgotten Password

This will mean you can still receive other emails that may be sent from DiS.

I would imagine similar filters are available for other email clients.

Sean is trying to get the forgotten password link updated so it's not possible to do this. Don't know how long it will be until something can be put in place, though.

Thanks
