mail.oriontransfer.net

This is the Orion Transfer mail server management interface.

Motivation

Hosting and billing customers for private email services.

Installation

Create an appropriate user for accessing the database:

CREATE USER IF NOT EXISTS 'http'@'localhost';
GRANT ALL PRIVILEGES ON vmail.* TO 'http'@'localhost';
FLUSH PRIVILEGES;

Setup sudo for computing disk usage, e.g. in /etc/sudoers.d/http:

http  ALL=(ALL) NOPASSWD: /usr/bin/du

Dovecot Setup

You'll want to configure Dovecot to interface with MySQL:

`/etc/dovecot/dovecot.conf`

auth_mechanisms = plain login
mail_location = mdbox:~/mail.mdbox
mail_uid = vmail
mail_gid = vmail

passdb {
	driver = sql
	args = /etc/dovecot/dovecot-sql.conf
}

protocols = imap

service imap-login {
	client_limit = 512
	inet_listener imap {
	port = 0
	}
	process_limit = 8
	service_count = 0
	vsz_limit = 128 M
}

ssl_cert = </etc/ssl/private/mail.oriontransfer.net.pem
ssl_key = </etc/ssl/private/mail.oriontransfer.net.key

userdb {
	driver = sql
	args = /etc/dovecot/dovecot-sql.conf
}

verbose_proctitle = yes

service auth {
	unix_listener /var/spool/postfix/private/auth {
		mode = 0660
		# Assuming the default Postfix user and group
		user = postfix
		group = postfix
	}
}

protocol lda {
	mail_plugins = $mail_plugins sieve
}

plugin {
	zlib_save = xz
	zlib_save_level = 4
}

# Enable zlib plugin globally for reading/writing:
mail_plugins = $mail_plugins zlib

namespace {
	separator = /
	inbox = yes
}

`/etc/dovecot/dovecot-sql.conf`

driver = mysql

connect = host=localhost dbname=vmail user=vmail password=foobar

password_query = SELECT password FROM accounts LEFT JOIN domains ON accounts.domain_id = domains.id WHERE accounts.local_part = '%n' AND domains.name = '%d' AND domains.is_enabled = 1 AND accounts.is_enabled = 1

user_query = SELECT mail_location AS mail, concat('/srv/mail/', domains.name, '/', accounts.local_part) AS home, 'vmail' AS uid, 'vmail' AS gid FROM accounts LEFT JOIN domains ON accounts.domain_id = domains.id WHERE accounts.local_part = '%n' AND domains.name = '%d' AND domains.is_enabled = 1 AND accounts.is_enabled = 1

# For using doveadm -A:
iterate_query = SELECT concat(accounts.local_part, '@', domains.name) AS username FROM accounts LEFT JOIN domains ON accounts.domain_id = domains.id WHERE domains.is_enabled = 1 AND accounts.is_enabled = 1

Postfix Setup

Postfix talks to Dovecot for authentication and virtual mailbox lookup:

`/etc/postfix/master.cf`

Talk to Dovecot for auth:

smtpd_sasl_type = dovecot
smtpd_sasl_path = /var/spool/postfix/private/auth
smtpd_sasl_auth_enable = yes
smtpd_use_tls=yes
smtpd_tls_auth_only=yes
smtpd_tls_cert_file=/etc/ssl/private/mail.oriontransfer.net.pem
smtpd_tls_key_file=/etc/ssl/private/mail.oriontransfer.net.key
smtpd_tls_session_cache_database = btree:/var/lib/postfix/smtpd_scache
smtpd_tls_session_cache_timeout = 3600s

`/etc/postfix/main.cf`

Use dovecot for local delivery, filter it via spamc.

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/bin/vendor_perl/spamc -f -u spamd -e /usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}

`/etc/postfix/virtual_mailbox_maps.cf`

user = vmail
password = foobar
dbname = vmail
query = SELECT 1 FROM accounts LEFT JOIN domains ON accounts.domain_id = domains.id WHERE accounts.local_part = '%u' AND domains.name = '%d' AND domains.is_enabled = 1
