Alexander - I've got gmail set up as an Account on Thunderbird, along with Virgin, but when I click on gmail, there isn't a cog on the right hand side. However, if I right click, on my gmail address in the local folders, I get a list of reading e-mail, Accounts and Advanced Features. There is a cog under accounts, headed View settings for this account. But there is nothing named Labels, nor is there a list as you suggest. However, under Advanced Features, there is Manage Folder Subscriptions. When I open that, there is a folder list and under that has Drafts, Inbox, Junk, then an overall folder called Gmail. This has All Mail (which is already unticked), Drafts, Spam, Sent Mail etc. and various personal folders, re family history, neighbourhood watch etc. where I keep e-mails until I've finished with them. There is no way of mention of Show in IMAP box, I'm just asked to subscribed or unsubscribe. If boxes are left unticked - like All Mail - then they are unsubscribed. I've no idea why Inbox, Drafts and Junk are under my e-mail address and Drafts and Spam are under Gmail. Ideally, I'd like them all under the one heading.
I'm just confused. I don't have this problem with Virgin and Thunderbird, and another problem is that Gmail is letting phishing mail through which Virgin never does.
