Почтовый сервер в связке Postfix, Dovecot

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 10.1

1. Подготовка.
прописываем хостнейм /etc/rc.conf
hostname="mail.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 группу vmail

# pw groupadd vmail -g 5000
# pw useradd vmail -g vmail -s /sbin/nologin -u 5000

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. Ставим 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/*.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';

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 : $CONF['setup_password'] = 'хеш';
Повторяем процедуру заведения суперадмина используя пароль_установки

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

6. Устанавливаем 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
