Repeating email

Dear All Postfix master..
Pls help, masalah ini sampai saat ini belum bisa terpecahkan juga, 
Postfix di server saya untuk beberapa domain tertentu, menerima email 
yang terus berulang sampai 70 x untuk email yg sama, padahal yg 
bersangkutan hanya mengirim sekali.
Please Help, I am dying Now.
Kalo ada info yang kurang ntar saya posting lagi, sembari saya 
kutak-katik disini.

ini log nya:
