mismatch sender id

[Jerry Hsu]

Dears,

My code already deployed to production for months.
But I got the error code "MismatchSenderId" at 11/15 and 11/22 till
now.

Do you know what it is?
Or any incident during these days?

Thanks.

nope. you need to set the sender_id in the client code with the email
address you registered to the c2dm servers (the one you use in the
http post to send messages).

I changed the error code to mismatch sender id to make it more clear
from invalid registration.

1) I am using an email - x...@gmail.com on client side. - I am able to get a registration id and sent to server.
2) On server I am using the same x...@gmail.com/password to authenticate and  get an auth token. I am sending a msg and am getting the mismatchsenderid as a response.

What am I doing wrong?
