Аутентификация, не работающая в Dovecot и PostgreSQL

Я хочу разместить свой собственный почтовый сервер на VPS, используя Postfix, Dovecot, LMTP и PostgreSQL. Я не могу отправлять сообщения из VPS с помощью команды mail, т. Е. Я не получаю эти письма на моей заменяющей учетной записи, и отправка электронной почты из учетной записи резервного копирования заканчивается ошибкой:

Undelivered Mail Returned to Sender This is the mail system at host mail.hubot.pl. 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 <hubot@hubot.pl> (expanded from <admin@hubot.pl>): host mail.hubot.pl[private/dovecot-lmtp] said: 550 5.1.1 <hubot@hubot.pl> User doesn't exist: hubot@hubot.pl (in reply to RCPT TO command) 

Я уже пытался изменить файлы конфигурации dovecota и postgresql pg_hba.conf и pg_ident.conf разными способами, а также объединить их с DNS без эффекта.

Это моя запись MX для hubot.pl:

 hubot@hubot-vps:~$ sudo cat /etc/postgresql/9.4/main/pg_hba.conf # PostgreSQL Client Authentication Configuration File # =================================================== # # Refer to the "Client Authentication" section in the PostgreSQL # documentation for a complete description of this file. A short # synopsis follows. # # This file controls: which hosts are allowed to connect, how clients # are authenticated, which PostgreSQL user names they can use, which # databases they can access. Records take one of these forms: # # local DATABASE USER METHOD [OPTIONS] # host DATABASE USER ADDRESS METHOD [OPTIONS] # hostssl DATABASE USER ADDRESS METHOD [OPTIONS] # hostnossl DATABASE USER ADDRESS METHOD [OPTIONS] # # (The uppercase items must be replaced by actual values.) # # The first field is the connection type: "local" is a Unix-domain # socket, "host" is either a plain or SSL-encrypted TCP/IP socket, # "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a # plain TCP/IP socket. # # DATABASE can be "all", "sameuser", "samerole", "replication", a # database name, or a comma-separated list thereof. The "all" # keyword does not match "replication". Access to replication # must be enabled in a separate record (see example below). # # USER can be "all", a user name, a group name prefixed with "+", or a # comma-separated list thereof. In both the DATABASE and USER fields # you can also write a file name prefixed with "@" to include names # from a separate file. # # ADDRESS specifies the set of hosts the record matches. It can be a # host name, or it is made up of an IP address and a CIDR mask that is # an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that # specifies the number of significant bits in the mask. A host name # that starts with a dot (.) matches a suffix of the actual host name. # Alternatively, you can write an IP address and netmask in separate # columns to specify the set of hosts. Instead of a CIDR-address, you # can write "samehost" to match any of the server's own IP addresses, # or "samenet" to match any address in any subnet that the server is # directly connected to. # # METHOD can be "trust", "reject", "md5", "password", "gss", "sspi", # "ident", "peer", "pam", "ldap", "radius" or "cert". Note that # "password" sends passwords in clear text; "md5" is preferred since # it sends encrypted passwords. # # OPTIONS are a set of options for the authentication in the format # NAME=VALUE. The available options depend on the different # authentication methods -- refer to the "Client Authentication" # section in the documentation for a list of which options are # available for which authentication methods. # # Database and user names containing spaces, commas, quotes and other # special characters must be quoted. Quoting one of the keywords # "all", "sameuser", "samerole" or "replication" makes the name lose # its special character, and just match a database or username with # that name. # # This file is read on server startup and when the postmaster receives # a SIGHUP signal. If you edit the file on a running system, you have # to SIGHUP the postmaster for the changes to take effect. You can # use "pg_ctl reload" to do that. # Put your actual configuration here # ---------------------------------- # # If you want to allow non-local connections, you need to add more # "host" records. In that case you will also need to make PostgreSQL # listen on a non-local interface via the listen_addresses # configuration parameter, or via the -i or -h command line switches. local mail all peer map=mailmap #host pgadmin mail 127.0.0.1/32 md5 # DO NOT DISABLE! # If you change this first entry you will need to make sure that the # database superuser can access the database using some other method. # Noninteractive access to all databases is required during automatic # maintenance (custom daily cronjobs, replication, and similar tasks). # # Database administrative login by Unix domain socket local all postgres peer # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all peer # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5 # Allow replication connections from localhost, by a user with the # replication privilege. #local replication postgres peer #host replication postgres 127.0.0.1/32 md5 #host replication postgres ::1/128 md5 [/syntax]

Надеюсь, кто-то поможет мне решить эту проблему.

One Solution collect form web for “Аутентификация, не работающая в Dovecot и PostgreSQL”

Вы используете предварительную выборку базы данных пользователей , которая может использоваться для уменьшения количества запросов в базе данных паролей, уже считывая информацию о пользователе во время аутентификации, но это работает только тогда, когда пользователь фактически аутентифицирован.

Для доставки почты LDA, очевидно, не будет аутентифицироваться, поэтому вам потребуется вторая конфигурация базы данных пользователей, которая читается из базы данных SQL. Вы уже настроили SQL-запрос в /etc/dovecot/dovecot-sql.conf , но не dovecot.conf конфигурацию второй пользовательской базы данных в dovecot.conf (со страницы wiki, связанной выше, но пути скорректированы в соответствии с вашей конфигурацией):

 passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } # The userdb below is used only by lda. userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf }
