hijinks 40 Report post Posted September 29, 2006 Ok.. so recently I moved photoblog.com off a old crappy server that had cpanel on a nice server that doesn't run cpanel. So I needed a system for virtual hosting for emails mainly. I've setup postfix+mysql+courier before and courier can be a GIANT bitch. So I looked into dovecot and was very happy. So lets start off.. lets download PostfixAdmin. As of writting this you can use the following since its the current version wget http://high5.net/postfixadmin/download.php?file=postfixadmin-2.1.0.tgz tar zxfv download.php?file=postfixadmin-2.1.0.tgz cd postfixadmin-2.1.0 ok my wget saved it as download.php.... your results may vary Ok now once its installed we want to import the basic DB layout into mysql. Edit the file if you want to change the user/pass.. but you will have to change it in other files below.. so just take note if you edit it. mysql -u root < DATABASE_MYSQL.TXT So that command is the default install of mysql that you didn't set a root password on.. use the -p flag if you did ok now that the layout is there lets get postfix and dovecot installed. Now the default version of postfix that ships with fedora/centos DOES NOT HAVE MYSQL FUNCTIONALITY BUILT IN. So this will be for centos or rhel you have to install the centos Plus version of it. wget http://mirror.trouble-free.net/centos/4/centosplus/i386/RPMS/postfix-2.1.5-4.2.RHEL4.mysql.centos4.i386.rpm rpm -ivh postfix-2.1.5-4.2.RHEL4.mysql.centos4.i386.rpm yum -y install dovecot Ok great all the needed stuff is installed. So lets add a vmail user to the system groupadd -g 901 vmail useradd -u 901 -g 901 vmail Then you want to edit /etc/postfix/main.cf and add this to the bottom. Take a note of /vmail change that to the location you want to store all your email in. virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf virtual_gid_maps = static:901 virtual_mailbox_base = /vmail virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_limit = 51200000 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 901 virtual_transport = virtual virtual_uid_maps = static:901 ok save the file and create a new file in /etc/postfix/mysql_virtual_alias_maps.cf and add the following user = postfix password = postfix hosts = localhost dbname = postfix table = alias select_field = goto where_field = address ok save the file and create a new file in /etc/postfix/mysql_virtual_domains_maps.cf and add the following user = postfix password = postfix hosts = localhost dbname = postfix table = domain select_field = domain where_field = domain #additional_conditions = and backupmx = '0' and active = '1' ok save the file and create a new file in /etc/postfix/mysql_virtual_mailbox_maps.cf and add the following user = postfix password = postfix hosts = localhost dbname = postfix table = mailbox select_field = maildir where_field = username #additional_conditions = and active = '1' ok save the file and create a new file in /etc/postfix/mysql_virtual_mailbox_limit_maps.cf and add the following user = postfix password = postfix hosts = localhost dbname = postfix table = mailbox select_field = quota where_field = username #additional_conditions = and active = '1' ok save the file and create a new file in /etc/postfix/mysql_relay_domains_maps.cf and add the following user = postfix password = postfix hosts = localhost dbname = postfix table = domain select_field = domain where_field = domain additional_conditions = and backupmx = '1' now save that and lets chown them chmod 640 /etc/postfix/mysql_* chgrp postfix /etc/postfix/mysql_* Now lets create the /vmail dir and give it the correct permissions mkdir /vmail chmod 771 /vmail chown vmail:vmail /vmail now lets restart or start postfix in this case we will start it service postfix start If you have sendmail on the machine already a nice little rpm to download is system-switch-mail once download run the command by the same name.. select postfix and it'll be running Now go back to the place you untared postfixadmin and point our browser to that location like http://jyiscool.com/postfixadmin/setup.php Make sure you pass all points.. then you want to remove the setup.php file Ok now in the postfixadmin dir do this cd admin You need to setup the .htaccess file. So edit .htaccess in that dir and it will look something like this AuthUserFile /some/dir/to/go/mail/admin/.htpasswd AuthGroupFile /dev/null AuthName "Postfix Admin" AuthType Basic <limit GET POST> require valid-user </limit> You want to change AuthUserFile to the path where that .htpasswd file is that you just put your postfixadmin app. Once thats installed delete the file and we will create a new one since we don't want to use the same admin user that is in there by default rm -rf .htpasswd htpasswd -c .htpasswd username Now edit the config.inc.php file cd .. mv config.inc.php-dist config.inc.php Basically you just have to change some defaults to suit your needs.. From there you should be able to access the admin error by entering the user/pass you just made and create a new domain and create some new users.. Once you have done that you should be able to use the local mail command to send off a test email to make sure its in the /vmail dir echo testing 1 2 3 | mail -s test user@jyiscool.com if you see a /vmail/user@jyiscool.com directory then it worked.. yayaya Now I like setting up new services like I like my women.. easy So create a new file called /etc/dovecot-mysql.conf with the following contents db_host = 127.0.0.1 db_port = 3306 db = postfix db_user = postfix db_passwd = postfix db_client_flags = 0 default_pass_scheme = PLAIN password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 901 AS uid, 901 AS gid FROM mailbox WHERE username = '%u' Save that and edit the /etc/dovecot.conf file and add the following at the bottom auth_userdb = mysql /etc/dovecot-mysql.conf auth_passdb = mysql /etc/dovecot-mysql.conf first_valid_uid = 501 default_mail_env = maildir:/vmail/%u i also turned off ssl.. I might enable it in the future and append to this howto.. but for now in my dovecot.conf there is ssl_disable = yes Now start dovecot service dovecot start You should not be able to grab that email you just sent that user via imap/pop3 Now make sure both get loaded on boot chkconfig dovecot on chkconfig postfix on Now I am pretty drunk now while doing this so there could be many errors.. deal with it 33 Quote Share this post Link to post Share on other sites

Here is few lines from main.cf virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cfvirtual_gid_maps = static:1001 virtual_mailbox_base = /opt/mail virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_mailbox_limit = 51200000 virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 1001 virtual_transport = virtual virtual_uid_maps = static:1001 # quota addon virtual_create_maildirsize = yes virtual_mailbox_extended = yes virtual_mailbox_limit_maps = mysql:/etc/postfix/mysql_virtual_mailbox_limit_maps.cf virtual_mailbox_limit_override = yes virtual_maildir_limit_message = Sorry, the user's maildir has overdrawn his diskspace quota, please try again later.

speeddemon92 1 Report post Posted March 7, 2010 Thanks man this is a life saver. I use Ubuntu and used their page which used courier and quickly found problems. I since found this page and have used it for the second time with success! (First time my server was hacked because I forgot to harden it Oh well, I learned better) I just set up my server for the second time just a few hours ago and is working now after looking at my error in the log. I just want to say thank you for this simple instruction page. Also if anyone ever has problems with your server and your postfix log says something about the mysql sockets like this "postfix/cleanup[4486]: warning: connect to mysql server localhost: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)" there is a quick fix. change this line in your mysql_* files from: hosts = localhost to: hosts = 127.0.0.1 this will help as linux sometimes forgets that it is localhost or if it is chrooted. 1 Quote Share this post Link to post Share on other sites

Dungeon-Dave 293 Report post Posted May 27, 2010 Looks like postfix can't pass the mail to dovecot. Is dovecot actually running? 1 Quote Share this post Link to post Share on other sites
