proxymap
in SQL/LDAP query mapsSet proxy_read_maps
in postfix, so that we can use proxymap(8)
daemon which
is part of postfix to reduce the number of connections to MySQL/LDAP and
greatly reduces system load.

NOTE: They are trusted subnets (amavisd-new default setting), mail sent from these subnets will be bypassed for anti-spam and anti-virus.
Convert some columns of policyd database from latin to utf8, so that we can
add non-ascii characters in description
column.
$ mysql -uroot -p policyd
mysql> ALTER TABLE blacklist MODIFY COLUMN _description CHAR(60) CHARACTER SET utf8;
mysql> ALTER TABLE blacklist_sender MODIFY COLUMN _description CHAR(60) CHARACTER SET utf8;
mysql> ALTER TABLE whitelist MODIFY COLUMN _description CHAR(60) CHARACTER SET utf8;
mysql> ALTER TABLE whitelist_dnsname MODIFY COLUMN _description CHAR(60) CHARACTER SET utf8;
mysql> ALTER TABLE whitelist_sender MODIFY COLUMN _description CHAR(60) CHARACTER SET utf8;
NOTE: Policyd database name is policyd
(on RHEL/CentOS) or postfixpolicyd
(on Debian/Ubuntu).
# --- BELOW ARE SHELL COMMANDS ----
# cd /etc/openldap/schema/ # Note: On Debian/Ubuntu, path is /etc/ldap/schema/
# cp iredmail.schema iredmail.schema.bak
# cd /root
# wget http://iredmail.googlecode.com/hg/tags/0.5.1/samples/iredmail.schema
# mv -i /root/iredmail.schema /etc/openldap/schema/
# /etc/init.d/ldap restart # Note: On Debian/Ubuntu, path is /etc/init.d/slapd
NOTE: New LDAP schema provides several new attributes, but it's backwards compatibility, it's SAFE to replace the old one without additional operations.
Prepend proxy:
to the beginnning of all LDAP lookup table definitions in
postfix configuration file: /etc/postfix/main.cf
. For example:
# Part of file: /etc/postfix/main.cf
# Old setting:
#virtual_alias_maps = ldap:/etc/postfix/ldap_virtual_alias_maps.cf
# New setting. Add 'proxy:'.
virtual_alias_maps = proxy:ldap:/etc/postfix/ldap_virtual_alias_maps.cf
Update dovecot settings to restrict POP3S & IMAPS in /etc/dovecot-ldap.conf
(on RHEL/CentOS) or /etc/dovecot/dovecot-ldap.conf
(on Debian/Ubuntu),
support domain alias and user shadow address.
# Part of file: dovecot-ldap.conf
# Old setting:
#base = ou=Users,domainName=%d,o=domains,dc=iredmail,dc=org
#user_filter = (&(mail=%u)(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=%Ls))
#pass_filter = (mail=%u)
# New setting (user_filter is same as pass_filter):
base = o=domains,dc=iredmail,dc=org
user_filter = (&(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=%Ls%Lc)(|(mail=%u)(&(enabledService=shadowaddress)(shadowAddress=%u))))
pass_filter = (&(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=%Ls%Lc)(|(mail=%u)(&(enabledService=shadowaddress)(shadowAddress=%u))))
Restarting Dovecot service is required.
# python
>>> import ldap
If it raises error message ImportError: No module named ldap
, you have to
install python-ldap module first.
# easy_install python-ldap==2.3.8
# wget http://iredmail.googlecode.com/hg/extra/update/updateLDAPValues_050_to_051.py
# Part of file: updateLDAPValues_050_to_051.py
uri = 'ldap://127.0.0.1:389'
basedn = 'o=domains,dc=iredmail,dc=org'
bind_dn = 'cn=Manager,dc=iredmail,dc=org'
bind_pw = 'passwd'
# python updateLDAPValues_050_to_051.py
Add domain alias support in postfix ldap lookup table file: /etc/postfix/ldap_virtual_mailbox_domains.cf
.
# Part of file: /etc/postfix/ldap_virtual_mailbox_domains.cf
# ---- Old setting ----
query_filter = (&(objectClass=mailDomain)(domainName=%s)(!(domainBackupMX=yes))(accountStatus=active)(enabledService=mail))
# ---- New setting ----
query_filter = (&(objectClass=mailDomain)(|(domainName=%s)(&(enabledService=domainalias)(domainAliasName=%s)))(!(domainBackupMX=yes))(accountStatus=active)(enabledService=mail))
Add missing service control in postfix ldap lookup table file: /etc/postfix/ldap_virtual_mailbox_maps.cf
:
# Part of file: /etc/postfix/ldap_virtual_mailbox_maps.cf
# OLD setting
#query_filter = (&(objectClass=mailUser)(mail=%s)(accountStatus=active)(enabledService=mail))
# NEW setting
query_filter = (&(objectClass=mailUser)(mail=%s)(accountStatus=active)(enabledService=mail)(enabledService=deliver))
Add shadowAddress
and employeeNumber
attribute names in
/etc/openldap/slapd.conf
(RHEL/CentOS) or /etc/ldap/slapd.conf
(Debian/Ubuntu) for access control and index.
# Part of file: slapd.conf
# OLD setting
#access to attrs="homeDirectory,mailMessageStore,mail,..."
# NEW setting
access to attrs="shadowAddress,employeeNumber,homeDirectory,mailMessageStore,mail,..."
# OLD setting
#index homeDirectory,mailMessageStore,mailForwardingAddress eq,pres
# NEW setting
index homeDirectory,mailMessageStore,mailForwardingAddress,shadowAddress,employeeNumber eq,pres
Add columns used for service control: pop3s, imaps, managesieve:
# mysql -uroot -p vmail
mysql> ALTER TABLE mailbox ADD COLUMN enableimapsecured TINYINT(1) NOT NULL DEFAULT '1';
mysql> ALTER TABLE mailbox ADD COLUMN enablepop3secured TINYINT(1) NOT NULL DEFAULT '1';
mysql> ALTER TABLE mailbox ADD COLUMN enablemanagesievesecured TINYINT(1) NOT NULL DEFAULT '1';
Add columns used to store default user quota size, per-domain default password length control. Will be used in iRedAdmin.
# mysql -uroot -p vmail
mysql> ALTER TABLE domain ADD COLUMN defaultuserquota BIGINT(20) NOT NULL DEFAULT '1024';
mysql> ALTER TABLE domain ADD COLUMN minpasswordlength INT(10) NOT NULL DEFAULT '0';
mysql> ALTER TABLE domain ADD COLUMN maxpasswordlength INT(10) NOT NULL DEFAULT '0';
proxymap
to improve performance and reliability under high load in PostfixPrepend proxy:
to the beginnning of all MySQL lookup table definitions in
postfix configuration file: /etc/postfix/main.cf
. For example:
# Part of file: /etc/postfix/main.cf
# Old setting:
#virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
# New setting. Add 'proxy:'.
virtual_alias_domains = proxy:mysql:/etc/postfix/mysql_virtual_alias_maps.cf
Update dovecot settings in /etc/dovecot-mysql.conf
(RHEL/CentOS) or
/etc/dovecot/dovecot-mysql.conf
(Debian/Ubuntu) to restrict POP3S/IMAPS
services.
# Part of file: dovecot-mysql.conf
# Old setting:
AND active='1' AND enable%Ls='1' AND expired >= NOW()
# New setting (Add '%Lc'):
AND active='1' AND enable%Ls%Lc='1' AND expired >= NOW()
