Virtual supaya di kenal

Saya coba test virtualdomain dikirimi email dari yahoo .. mesti hasilnya dapat 
replay kayak di bawah ini:
Bagaimana yah supaya virtual domain yg saya buat di postfix pake' postfixadmin di kenali dari luar.. 
Mau ngirim ke virtual aku-y40lTQNuVJddtzx+TpIdMQ@xxxxxxxxxxxxxxxx koq musti ke aku@xxxxxxxxxx
DNS .. untuk MX dari setting awe.aei.co.id --> aei.co.id dan awe.aei.co.id --> 
awe.aei.co.id ..
CNAME kayaknya sudah di kenali
awe.aei.co.id CNAME ke aei.co.id

Apakah ada seetingan dari ppostfix untuk hal ini .. ataukah harus membuat alias 
sendiri ..
Mohon advicenya ..

Salam
