Estou configurando meu próprio servidor de e-mail Ubuntu em casa (postfix-mysql-dovecot-roundcube) com um domínio MX registrado (aqui no meu exemplo será "domain.com").

Meu main.cf:

# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname Welcome
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings

Eu defini todos os outros arquivos para o postfix-mysql e dovecot, seguindo alguns tutoriais online. Eu posso receber e-mails externos, mas eles estão presos na fila de postix. Quando tento recuperá-los, recebo essas linhas de registro:

Alguma ideia?

O arquivo de configuração dovecot-sql.conf.ext:

# This file is commonly accessed via passdb {} or userdb {} section in

# http://wiki2.dovecot.org/AuthDatabase/SQL

# Database driver: mysql, pgsql, sqlite
driver = mysql

connect = host=db dbname=mail_db user=usermail password=password

password_query = SELECT password FROM mailbox WHERE username = '%u'

user_query = SELECT '/mail/vmail/%d/%n' as home, 150 AS uid, 8 AS gid FROM mailbox WHERE username = '%u'

# If you wish to avoid two SQL lookups (passdb + userdb), you can use
# userdb prefetch instead of userdb sql in dovecot.conf. In that case you'll
# also have to return userdb fields in password_query prefixed with "userdb_"
# string. For example:
#password_query = \
#  SELECT userid AS user, password, \
#    home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \
#  FROM users WHERE userid = '%u'

# Query to get a list of all usernames.
#iterate_query = SELECT username AS user FROM mailbox
