I was observing this since a week now, so thought of posting about it 🙂

Software: Gmail Beta

Bug Description:

Mail which is deleted forever re-appears in the spam folder in Gmail.

How to reproduce:

Very  easy. Keep your Gmail spam folder open in a window. Wait for a spam to arrive or send a spam mail from your another email account to your Gmail account. Let Gmail show automatically that there is a mail in Spam folder. Don’t click on Spam in Index. Now click “Delete all spam messages now” and then click Ok when it says that the messages will be deleted forever. After you click Ok, the page will reload and the *SAME* mail will be there 🙂

Proof:

If you think I have gone mad and talking in air. Here is a *video* proof 😛 Checkout the timestamp for the mail and the running clock in the top right corner.
