I`m developing a mailing list system and wanted to test it against big list of recipients. Is there a way configuring postfix to accept any recipients address within some test domain and deliver it to a single specified user mailbox? No other users/mailbox required. System will be testing-purpose only and accessible only from local network.

If it cant be done in postfix, is there any other possibilities using other mail server software?

You have to create a catch all email account. I am guessing you are using virtual domains on your Postfix installation. In your virtual alias table you just have to define:     some_user              some_user

And all mail that comes to domain will be saved in the account.

Yes, you want to create a canonical lookup table. See the canonical manpage.
