I've a couple of e-mail addresses, one with Plusnet the other with GMX (thru Thunderbird). Whenever I send an e-mail the Plusnet one comes up as the default sender, I'd like to change this to GMX. Anybody know how do I do this?
Open Thunderbird and click on the 'Tools' menu and select 'Account Settings...'. A box will pop up showing your account settings. Select the address you want to make your default (GMX) and then click on 'Account Actions' at the bottom. Select 'Set as Default' then click 'OK'.
