Deleting 3000 Sent emails on Telstra webmail at one selection instead of 50 at a time
Using Telstra.com webmail, I notice there are over 3000 SENT emails building up. The system only allows you to delete 50 emails at a time which will take ages. Request advice on how to delete all Webmail SENT emails without having to go through all the time and trouble of 50 at a time.
Also with all those webmail SENT emails building up does that slow down my computer?
