[postfix-users] Recipient address reject ed: User unknown in virtual mailbox table

[Bonar Gultom]

Dear all,
saya ingin menanyakan bagaimana caranya apabila address yang tidak ada di 
virtual mailbox dapat di-reject. soalnya di mail log hal seperti di bawah ini 
selalu muncul:

Aug 23 04:02:58 s_lo...@arsenal postfix/smtpd[30017]: NOQUEUE: reject: RCPT from
 unknown[92.46.2.117]: 550 5.1.1 <e...@matrikstama.com>: Recipient address

saya menggunakan postfixadmin, dan mail server saya menangani beberapa domain.
postfix yang saya gunakan adalah postfix-2.4.1 dan os rhel 3.

terima kasih atas bantuannya.

 Warm Regards,
