Hi Zhang,

Please check the above log email daily sent to my postmaster inbox. I had upgrade from 0.9.2 to 0.9.3 according to your instruction.

I noticed that the content of this email is quite different from the previous ones when I still at 0.9.2.

Should I be worry because of something went wrong or do I need to fix anything?

Thank you and best regards,
Quy
