Can not submit extension via Travis CI and receive "email account is not allowed" message

I try to submit my extension with Travis CI, but I receive error message below:

The email address used for your account is not allowed for add-on submission.

And I try to sign the developer addon agreement from https://addons.mozilla.org/zh-TW/developers/addon/agreement/, but receive the same error message also.

Anyone can help me to figure out what’s going wrong or I miss something else?

Please email amo-admins AT mozilla DOT com for help.
