莫名email - Google

這幾天我gmail一直有奇怪的信件，我上網搜尋一下，發現是被盜帳號，可是我沒有用過
gmail當奇摩的備用帳號，請問有人知道是怎麼回事嗎?

謝謝

以下是信件內容

名稱: Returned Mail: 550 Requested action not taken: mailbox unavailab le

The original message was received at Thu, 04 Dec 2014 23:05:11 +0800 (CST)
from 我的gmail

---The following addresses had delivery errors---


[email protected] [550 Requested action not taken: mailbox unavailable]

這是我在奇摩看到的
