gmail Mail Delivery Subsystem - Google

這二天我的每一封信都回到
-------------------------------------
寄件人:Mail Delivery Subsystem

內容:

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

[email protected]

Technical details of permanent failure:
Account disabled
--------------------------------------

而我的google帳號是daXXXtw

並沒有"2"這個字元

而我的每封信的收信人均是daXXXtw,不是daXXXtw2,

每封信都有一封Mail Delivery Subsystem的信..

請問有人知道是什麼事嗎?謝謝大家..
