For some, it was true!!
In a real bizarre incident, about 60 Gmail account holder's Gmail data - emails, contacts etc. - all had been wiped out forever!
Those 60 users might not have dreamt this, since Gmail had redefined using e-mail - Never delete e-mails, instead, archive it and search.
The incident is related to a security flaw in FireFox 2.0 browser, since these users were using it, and it is reported that they receive following message:
"This is not a mistake. All your emails and contacts have been deleted on purpose. This was a malicious attack and not an error. Have a nice day. =)"
So, if you are using Gmail, awake, and atleast, backup some really important e-mails and contact information. Gmail supports pop3 access, so better configure a mail client, and periodically download your mails to a safe location.
There is a tool called Gmail POP troubleshooter that you can download and run to auto configure your Outlook Express to download email from your Gmail Account.
