Dear Amit TanKThanks for the reply.After run the diagnostic log, I do found the similar error same as the KB you given.I have request the hotfix and will apply it once I can get it.Thanks.Best regards

Dear Amit Tank,I have the hotfix, but the hotfix not applicable to my exchange. Its only intended to exchange SP1 but mine SP2.I still can't figure out why only this sender's email are unable to deliver to user account.I use mail hosting mailbox to resend the said mail into different account, but still the same. Email retry in local.Couldnt be database corrupted. And I didn't migrate or moved mailbox. Just this email can't get to all user mailbox.Any other advise?
