Bevezető

Jelen leírás ubuntu 5.10-hez ad segítséget.
Ubuntu server telepítést használtam.

PostgreSql-t használok (mert én ebben bízok :) ), de a rendszer használható mysql-el is.

A levél terveink szerint a következő útvonalat fogja bejárni:

postfix[25]-> amavis[10024] -> postfix[10025]-> dspam[10026] -> postfix[10027] -> maildop -> courier imap/pop3

Képességek

• Több domain kezelése
• Virtuális userek
• User quota
• Vírusszűrés
• Spam Szűrés
• Imap / Pop3 hozzáférés
• Authentikált smtp szolgáltatás
• Secure smtp (TLS)

Összetevők

postfix, amavis, clamav, dspam, courier (imap/pop/maildrop), postgresql

Kezdő lépések

Hozzunk létre egy új felhasználót, ennek a nevében lesznek tárolva a levelek..

sudo adduser --no-create-home --system  --disabled-login vmail

Készítsük el a maildir-ek tárolókönyvtárát.

sudo mkdir -p /var/virtuals/mail
sudo chown -R vmail:users /var/virtuals/mail

Ha még nem módosítottuk idáig a /etc/apt/sources.list file-t akkor tegyük meg.

sudo apt-get update
sudo apt-get upgrade

Postgresql telepítése

apt-get install postgresql-8.0 postgresql-client-8.0 postgresql-common postgresql-contrib-8.0

Postgresql beállítása

Állítsuk be a localhost kapcsolatot....
Szerkesszük a /etc/postgresql/8.0/main/pg_hba.conf file-t.

host    all         all         127.0.0.1     255.255.255.255    password

Szerkesszük a /etc/postgresql/8.0/main/postgresql.conf file-t, és az ssl- állítsuk false-ra

ssl = false

Indítsuk ujra a szervert

sudo /etc/init.d/postgres restart

Hozzunk létre egy adatbázis usert, mondjuk isp_mail néven:

sudo -u postgres createuser isp_mail --no-adduser --createdb --pwprompt

Késöbb majd megvonjuk a jogokat...
Hozzuk létre az adtabázist:

createdb --encoding UNICODE --owner isp_mail --host 127.0.0.1 --username=isp_mail --password

Majd adjunk hozzá plpgsql-t

createlang --dbname=isp_mail --username=isp_mail -W plpgsql --host 127.0.0.1

Dspam telepítése

Sajnos ez csak forrásból megy jelenleg.
Csináltam belőle deb-et, aki lusta használja azt: dspam-3.6.1.tar.gz dspam_3.6.1-1_i386.deb
Biztos ami ziher belefordítottam a mysql, sqlite, db4 és hash támogatást is.
