That wiki does my head in.
Okay, here's the deal:
I just want one forward address email@example.com. I don't want to use webmail, I don't want it to store the email on the server. I just want firstname.lastname@example.org to automatically send all mail to that address to my gmail account.
Will this disable webmail entirely? If I uncheck the 'deliver to this mail box' box and just mark will be delivered to these email addresses and put in my gmail account? Or do I have to disable webmail through the Webmail tab?
