Помогите!
Нужно настроить виртуальные домены.
Всё делал по мануалам.

Если отправить письмо на user1@virtual.domain.ru приходи следующее сообщение

This is the mail system at host.

I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can delete your own text from the attached returned message.

                   The mail system

<user1@virtual.domain.ru>: User unknown in virtual alias table

Если из файла virtual убрать записи, то возвращается 550 как и должно быть.

postconf -n

Файл virtual

user1@virtual.domain.ru user2

Ломаю голову второй день.
