Постфикс + MySQL + голубятня + postfixadmin - почта прибывает в локальных пользователей

Я пытаюсь настроить почтовый сервер с виртуальными пользователями.

Я могу:

• вход в систему в roundcube,
• отправьте почту в Gmail

но когда я отправляю сообщения в свой собственный домен, письма прибывают в локальных пользователей.

Почта была в/var/mail, но в постфиксе и голубятне файлы конфигурации находятся в/var/vmail

Постфиксная конфигурация:

postconf -n

alias_database = hash:/etc/aliases
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
inet_interfaces = all
mailbox_size_limit = 0

Конфигурация голубятни:

doveconf -n

hosts = 127.0.0.1
dbname = mail

select_field = CONCAT(domain, '/', local_part)

У кого-либо есть какие-либо предложения?
