My BT email hacked?

[Technical Ben]

Just had Thunderbird tell me my pass/user name is not working. Going in through the webmail I get a notification of a "unusual activity". I'll be mad if it's been hacked.

Hopefully they're being over cautious.

They're moving from Yahoo to a different provider for the btinternet.com domain's email. There are bound to be problems.

And, yes, a lot of Yahoo hosted (including btinternet) email accounts have been hacked.

Yeah, did it again today. 
Also, had spam flagged mail that was not spam, and I was certain I had set it to "download anyway" to prevent false positives. Found an email from 2 weeks ago in there.

The problem is that every day I get lots of hoax e-mails purporting to come from BTYahoo inviting me to click on a link to upgrade my account.  They are all phishing for passwords and take control of your account as soon as you fall for the scam.  Once you enter your password into the link, they will change it and lock you out.  They will then e-mail all your contacts to tell them you are stranded abroad and require money to be forwarded by Western Union.  If you reply then you are replying direct to the scammers not the genuine account holder.  Unfortunately BTYahoo is currently axing thousands of disused accounts in order to free up e-mail addresses and they are sending warnings to all their customers to log in and change their password or lose the account.  I have no idea how you are supposed to tell which is the genuine e-mail!
