Почтовый сервер в связке Postfix, Dovecot

Материал из megapuper
Перейти к: навигация, поиск

При установке будем ориентироваться на этот мануал: http://dummyluck.com/page/pochtovyi_server_nastroika_opisanie
Настройку будем производить для сервера с одним доменом. Система FreeBSD 10.2


1. Подготовка
прописываем хостнейм /etc/rc.conf
hostname="servmp.megapuper.ru"


делаем изменения в хостах /etc/hosts

127.0.0.1         localhost
109.172.52.114	  megapuper.ru
109.172.52.114    mail.megapuper.ru


создаём пользователя и добавляем его в группу mail

# pw useradd mail -g mail -s /sbin/nologin -u 1000
# pw groupmod mail -m mail

сразу отключаем sendmail
/etc/rc.conf

sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"

/etc/periodic.conf

daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"


2. Установка Nginx, MySQL, PHP, PHP-extension. Этот web-сервер будет использоваться для PostfixAdmin

Здесь коротко, ибо уже тыщу раз ставилось)


Nginx cтавим из пакетов

# pkg install nginx


основной конфиг /usr/local/etc/nginx/nginx.conf

user www;
worker_processes  2;
pid        /var/run/nginx.pid;
events {
worker_connections  1024;
}

http {
     access_log    /var/log/nginx/access.log;
     error_log     /var/log/nginx/error.log;

     include       /usr/local/etc/nginx/mime.types;
     default_type  application/octet-stream;

     sendfile on;
     tcp_nopush on;
     tcp_nodelay on;
     keepalive_timeout  65;
     client_max_body_size 5m;
     server_names_hash_bucket_size 64;
     types_hash_max_size 2048;
     types_hash_bucket_size 64;
     include /usr/local/etc/nginx/conf.d/*.conf;
}


конфиг виртуального хоста /usr/local/etc/nginx/conf/postfix.conf

server {
        listen 80;
        server_name postfix.megapuper.ru;

root /usr/local/www/postfix;
        index index.php index.html index.htm;

        access_log /var/log/nginx/postfix.access.log;
        error_log  /var/log/nginx/postfix.error.log;

location / {
#        try_files $uri $uri/ /index.php?$uri&$args;
        }

location ~ \.php$ {
    fastcgi_pass   127.0.0.1:10000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
    fastcgi_intercept_errors on;
    include fastcgi_params;
        }
    }


PHP и нужные PHP-extension тоже ставим из пакетов

# pkg install php55
# pkg install php55-* (пригодятся php55-ctype php55-dom php55-gd php55-hash php55-iconv php55-imap php55-json php55-mbstring php55-mcrypt php55-mysql php55-mysqli php55-session php55-xml)


конфиг php-fpm /usr/local/etc/php-fpm.conf

[global]
error_log = /var/log/php/php-fpm.log
pid = /var/run/php-fpm.pid
log_level = notice
include=/usr/local/etc/php/*.conf


конфиг для виртуального хоста /usr/local/etc/php/postfix.conf

[postfix]
prefix = /usr/local/www/$pool
listen = 127.0.0.1:10000
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0660
user = www
group = www
pm = dynamic
pm.max_children = 4
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 100
;pm.status_path = /status/php-fpm/$pool
request_terminate_timeout = 0
request_slowlog_timeout = 1m
slowlog = /var/log/php/$pool.slow.log
catch_workers_output = yes


MySQL тоже из пакетов

# pkg install mysql56-server


простенький конфиг /etc/my.cnf

[mysqld]
bind-address=127.0.0.1

В конфигах, где используется подключение к базе указываем хост 127.0.0.1

После этого имеем готовый web-сервер можно переходить к установке PostfixAdmin


3. Установка PostfixAdmin

Скачиваем последнюю версию отсюда http://sourceforge.net/projects/postfixadmin/ и заливаем на web-сервер


создаём базу и даём права пользователю

> create database postfix character set utf8 collate utf8_general_ci;
> grant all on postfix.* to postfix@127.0.0.1 identified by 'пароль';


Папка для логов

# mkdir /var/log/postfixadmin
# chown www:www /var/log/postfixadmin

Правим основной конфиг PostfixAdmin config.inc.php
Spoiler


Выставляем права

# chown -R www:www /usr/local/www/postfix


Теперь заходим на http://postfixadmin/setup.php и видим, что запустилась установка
Если все условия установки выполнены, то в базе создадутся необходимые таблицы и будет предложено создать суперадмина.

В поле Setup password вводим пароль из config.inc.php: $CONF['setup_password'] = 'пароль_установки';
Заполняем остальные поля, и после нажатия кнопки Создать сгенерится хэш.

Этот хеш надо вставить в config.inc.php вместо пароля установки: $CONF['setup_password'] = 'хеш';
Повторяем процедуру заведения суперадмина используя пароль_установки

После создания суперадмина временно оставляем PostfixAdmin(так как без postfix и dovecot ящики создаваться не будут)

Закрываем страницу установки

$CONF['configured'] = false;


6. Установка Postfix

Postfix ставим из портов, т.к. пакет ставится без поддержки mysql

# cd /usr/ports/mail/postfix
# make install clean
[X] MYSQL, PCRE, SASL2, TLS
CYRUS-SASL [X] MYSQL, CRAM, DIGEST, LOGIN, PLAIN

По окончании установки активируем postfix

Would you like to activate Postfix in /etc/mail/mailer.conf [n]? y

Заведём нужные aliases /etc/aliases

www:    postmaster@megapuper.ru

Инициализируем базу алиасов

# newaliases


Рихтуем основные конфиги postfix
первый /usr/local/etс/postfix/main.cf
Spoiler


второй конфиг/usr/local/etс/postfix/master.cfоставляем дефолтным
Spoiler


Создаём таблицы данных формата "hash" и базы с помощью команды postmap
Необходимо создать файлы и базы со списками, которые были подключены в конфиге выше, даже если они будут пустыми

# touch aliases_lmtp
# touch aliases_smtp_output
# postmap aliases_lmtp
# postmap aliases_smtp_output


Создаём файлы, хранящие SQL-запросы, проверяя имена таблиц и полей (в очередной версии PostfixAdmin они могут измениться)

[/usr/local/etc/postfix/maps/mysql_virtual_maps.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT username FROM mailbox WHERE username='%s' AND active = '1'
[/usr/local/etc/postfix/maps/mysql_virtual_domains.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT domain FROM domain WHERE domain = '%s' AND backupmx = '0' AND active = '1'
[/usr/local/etc/postfix/maps/mysql_virtual_alias_maps.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT goto FROM alias WHERE address='%s' AND active = '1'
[/usr/local/etc/postfix/maps/mysql_virtual_alias_domain_maps.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT CONCAT('%u', '@', target_domain) FROM alias_domain WHERE alias_domain = '%d' AND active = 1
[/usr/local/etc/postfix/maps/mysql_bcc_domain_maps.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT 'bccsnd+bccflag@megapuper.ru' FROM domain WHERE domain='%d' AND active = '1'
[/usr/local/etc/postfix/maps/mysql_bcc_mailbox_maps.cf]

user = postfix
password = пароль
hosts = 127.0.0.1
dbname = postfix
query = SELECT CONCAT('%u', '+bccflag', '@', '%d') FROM mailbox WHERE username='%s' AND active = '1'


Выставляем права на конфиги

# chgrp postfix /usr/local/etc/postfix/*.cf
# chgrp postfix /usr/local/etc/postfix/maps/*.cf
# chmod u=rw,g=r,o= /usr/local/etc/postfix/*.cf
# chmod u=rw,g=r,o= /usr/local/etc/postfix/maps/*.cf


Рестартим postfix

# /usr/local/etc/rc.d/postfix restart


7. Установка Dovecot
Dovecot ставим из портов

# cd /usr/ports/mail/dovecot2/
# make install clean
[X] MYSQL


Устанавливаем поддержку языка Sieve в Dovecot(включает в себя настройку скриптов пользователями)

# pkg install dovecot-pigeonhole


Настраиваем конфиги dovecot

[/usr/local/etc/dovecot/dovecot.conf]

# Enable installed protocols
#!include_try /usr/share/dovecot/protocols.d/*.protocol
protocols = imap lmtp sieve
 
!include conf.d/*.conf

auth_mechanisms = plain

!include auth-sql.conf.ext


[/usr/local/etc/dovecot/conf.d/10-director.conf]

service director {
  unix_listener login/director {
    #mode = 0666
  }
  fifo_listener login/proxy-notify {
    #mode = 0666
  }
  unix_listener director-userdb {
    #mode = 0600
  }
  inet_listener {
    #port = 
  }
}
# Enable director for the wanted login services by telling them to
# connect to director socket instead of the default login socket:
service imap-login {
  #executable = imap-login director
}
#service pop3-login {
  #executable = pop3-login director
#}
# Enable director for LMTP proxying:
protocol lmtp {
  #auth_socket_path = director-userdb
}


[/usr/local/etc/dovecot/conf.d/10-logging.conf]

#login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c
#login_log_format = %$: %s
#mail_log_prefix = "%s(%u): "
# Format to use for logging mail deliveries. You can use variables:
#  %$ - Delivery status message (e.g. "saved to INBOX")
#  %m - Message-ID
#  %s - Subject
#  %f - From address
#  %p - Physical size
#  %w - Virtual size
#deliver_log_format = msgid=%m: %$


Подготовим каталоги

# mkdir /var/lib/dovecot/virtual
# mkdir /var/lib/dovecot/virtual/Folder
# chown -R vmail:vmail /var/lib/dovecot/virtual
# chmod -R 700 /var/lib/dovecot/virtual


Создаём Файл с фильтрами для виртуального каталога(для каталога Folder)

[/var/lib/dovecot/virtual/Folder/dovecot-virtual]

Примеры ACL
Следующая настройка запрещает пользователю всё, кроме чтения/просмотра/удаления, но разрешает сохранение для LDA

В каталоге с именем домена указываем ACL для папки ".Sent".

[/usr/local/etc/dovecot/acl/megapuper.ru/Sent]

owner lrwstpe

Аналогично можно настроить остальные папки (подробности - в заметке по ссылке чуть выше)
Закрываем доступ для всех кроме LDA к файлу ".dovecot.lda-dupes", который может быть виден в MUA как фантомная папка "lda-dupes":

# mkdir /usr/local/etc/dovecot/acl/megapuper.ru/dovecot/

ВАЖНО! - точка воспринимается как маркер вложенной папки.

# mv /usr/local/etc/dovecot/conf.d/auth-deny.conf.ext /usr/local/etc/dovecot/conf.d/auth-deny.conf.ext_
# mv /usr/local/etc/dovecot/conf.d/auth-ldap.conf.ext /usr/local/etc/dovecot/conf.d/auth-ldap.conf.ext_
# mv /usr/local/etc/dovecot/conf.d/auth-master.conf.ext /usr/local/etc/dovecot/conf.d/auth-master.conf.ext_
# mv /usr/local/etc/dovecot/conf.d/auth-passwdfile.conf.ext /usr/local/etc/dovecot/conf.d/auth-passwdfile.conf.ext_

# mv /usr/local/etc/dovecot/conf.d/auth-system.conf.ext /usr/local/etc/dovecot/conf.d/auth-system.conf.ext_
# mv /usr/local/etc/dovecot/conf.d/auth-vpopmail.conf.ext /usr/local/etc/dovecot/conf.d/auth-vpopmail.conf.ext_


Меняем права и владельца конфигов:

# chgrp vmail /usr/local/etc/dovecot/*.conf
# chmod g+r /usr/local/etc/dovecot/*.conf
# chgrp vmail /usr/local/etc/dovecot/*.ext
# chmod g+r /usr/local/etc/dovecot/*.ext
# chgrp vmail /usr/local/etc/dovecot/conf.d/*.conf
# chmod g+r /usr/local/etc/dovecot/conf.d/*.conf
# chgrp vmail /usr/local/etc/dovecot/conf.d/*.ext
# chmod g+r /usr/local/etc/dovecot/conf.d/*.ext


Теперь можно вернуться к PostfixAdmin и приступить к созданию доменов и ящиков
