Issues Fixed & Notify

LDAP backend only: Remove unnecessary ldap lookup in postfix (2009.07.26):

Remove ldap_virtual_mailbox_maps.cf in Postfix virtual_mailbox_maps.

# OLD setting
#virtual_mailbox_maps = ldap:/etc/postfix/ldap_accounts.cf, ldap:/etc/postfix/ldap_virtual_mailbox_maps.cf

# NEW setting
virtual_mailbox_maps = ldap:/etc/postfix/ldap_accounts.cf

Fixed: incorrect file permission on sa-update cron job

# chmod 0644 /etc/cron.d/sa-update

Fixed: different timezone in log file

Copy /etc/localtime to /var/spool/postfix/etc/ solves this issue:

# cp /etc/localtime /var/spool/postfix/etc/

Reference: Confusing timestamp in /var/log/secure (UTC time instead of localtime)

OpenLDAP backend only: Use the latest iRedMail LDAP schema file

`userPassword` and `accountStatus` are optional for objectclass `mailAdmin` (2008.03.25).

Please use the newest schema file to replace the old one:

Backup old schema file (we assume you backup it to /opt/backup/ directory):

# cp /etc/openldap/schema/iredmail.schema /opt/backup/

Use new version to replace the old one:

# cd /tmp/
# wget http://iredmail.googlecode.com/svn/trunk/iRedMail/samples/iredmail.schema
# rm -f /etc/openldap/schema/iredmail.schema
# mv /tmp/iredmail.schema /etc/openldap/schema/
# /etc/init.d/ldap restart

attribute `domainStatus` is deprecated.

Add new attribute accountStatus for each mail domain with phpLDAPadmin or other LDAP admin tool.
Change below files to use accountStatus instead.
- /etc/postfix/ldap_virtual_mailbox_domains.cf
- /etc/postfix/ldap_relay_domains.cf
- /etc/postfix/ldap_transport_maps.cf
- /etc/postfix/ldap_recipient_bcc_maps_domain.cf
- /etc/postfix/ldap_sender_bcc_maps_domain.cf
Send mail to exist mail user and make sure accountStatus works for you.
Delete attribute domainStatus in each domain.

Fixed incorrect OpenLDAP ACL (2009.03.23)

Edit /etc/openldap/slapd.conf, add several lines like below:

#
# Allow users to access their own domain subtree.
#
access to dn.regex="domainName=([^,]+),o=domains,dc=iredmail,dc=org$"
    by anonymous                    auth
    by self                         write
    by dn.exact="cn=vmail,dc=iredmail,dc=org"   read
    by dn.exact="cn=vmailadmin,dc=iredmail,dc=org"  write
    by dn.regex="mail=[^,]+,ou=Users,domainName=$1,o=domains,dc=iredmail,dc=org$" read
    by dn.regex="mail=[^,]+@$1,o=domainAdmins,dc=iredmail,dc=org$" read     # <-- Add this line.
    by users                        none

#
# Enable vmail/vmailadmin.
#

    by dn.exact="cn=vmailadmin,dc=iredmail,dc=org"  write
    by dn.regex="mail=[^,]+,domainName=$1,o=domains,dc=iredmail,dc=org$" read
    by users                        read

Fixed incorrect pysieved config file ownership. 2009.03.18

# chown vmail:vmail /etc/pysieved.ini
# /etc/init.d/pysieved restart

Improvements and Updates

Apache

Add /var/www/html/robots.txt file to disallow search engines. Content:

User-agent: *
Disallow: /mail
Disallow: /webmail
Disallow: /roundcube
Disallow: /phpldapadmin
Disallow: /ldap
Disallow: /mysql
Disallow: /phpmyadmin
Disallow: /awstats

PHP

Set disable_functions in /etc/php.ini. Thanks david(at)knapp(dot)org.

disable_functions = show_source, system, shell_exec, passthru, exec, phpinfo, proc_open

MySQL backend special

Add column to set mail storage base directory. Warning: Please replace /home/vmail below to fit your environment.

# mysql -uroot -p vmail
mysql> ALTER TABLE mailbox ADD COLUMN storagebasedirectory VARCHAR(255) DEFAULT '/home/vmail';

Alter vmail.enablesieve to vmail.enablemanagesieve:

# mysql -uroot -p vmail
mysql> ALTER TABLE mailbox CHANGE COLUMN enablesieve enablemanagesieve TINYINT(1);

Due to this change, you have to add one more parameter in /etc/pysieved.ini:

[Dovecot]
service = managesieve

Add new columns in vmail.mailbox table:

# mysql -uroot -p vmail
mysql> ALTER TABLE mailbox ADD COLUMN employeeid VARCHAR(255) DEFAULT NULL;
mysql> ALTER TABLE mailbox ADD COLUMN lastlogindate DATETIME NOT NULL DEFAULT '0000-00-00 00:00:00';
mysql> ALTER TABLE mailbox ADD COLUMN lastloginprotocol CHAR(255) NOT NULL DEFAULT '';

OpenLDAP backend special

Add one enabledService=forward in mail forwarding address lookup: /etc/postfix/ldap_virtual_alias_maps.cf.

query_filter    = (&(mail=%s)(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=forward))

Index more LDAP attributes in /etc/openldap/slapd.conf:

index domainAdmin,domainGlobalAdmin,domainBackupMX    eq,pres
index listAllowedUser,accessPolicy eq,pres
index memberOfGroup eq,pres

After added above line, please stop openldap and run slapindex in database directory:

# /etc/init.d/ldap stop
# cd /var/lib/ldap/iredmail.org/
# slapindex
# chown ldap:ldap *
# /etc/init.d/ldap start

Postfix

LDAP backend only: Mail group/list implemented of LDAP is changed.
- objectClass mailUser has a new attribute: memberOfGroup, used to store group name (a valid email address).
- Mail group lookup maps in postfix must be changed too. modify your /etc/postfix/main.cf:

virtual_alias_maps =
    ldap:/etc/postfix/ldap_virtual_alias_maps.cf,
    ldap:/etc/postfix/ldap_virtual_group_maps.cf    # Add this lookup file.

Create /etc/postfix/ldap_virtual_group_maps.cf:

server_host     = 127.0.0.1
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = cn=vmail,dc=iredmail,dc=org
bind_pw         = KrxIkebDaRWb81yHdetBPt0UXC6NVZ
search_base     = domainName=%d,o=domains,dc=iredmail,dc=org
scope           = sub
query_filter    = (&(memberOfGroup=%s)(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=deliver))
result_attribute= mail
debuglevel      = 0

Remove (objectClass=mailList) in query_filter line in /etc/postfix/ldap_virtual_alias_maps.cf:

#query_filter    = (&(mail=%s)(accountStatus=active)(enabledService=mail)(enabledService=deliver)(|(objectClass=mailList)(objectClass=mailAlias)(&(objectClass=mailUser)(enabledService=forward))))
query_filter    = (&(mail=%s)(accountStatus=active)(enabledService=mail)(enabledService=deliver)(|(objectClass=mailAlias)(&(objectClass=mailUser)(enabledService=forward))))

LDAP backend only: Add bcc control in bcc lookup. Warning: Do NOT forget to add enabledService=senderbcc and enabledService=recipientbcc for all domains/users allowed bcc feature.

File: /etc/postfix/ldap_sender_bcc_maps_domain.cf.

query_filter    = (&(domainName=%d)(objectClass=mailDomain)(domainStatus=active)(enabledService=mail)(enabledService=senderbcc))

File: /etc/postfix/ldap_recipient_bcc_maps_domain.cf.

query_filter    = (&(domainName=%d)(objectClass=mailDomain)(domainStatus=active)(enabledService=mail)(enabledService=recipientbcc))

File: /etc/postfix/ldap_sender_bcc_maps_user.cf.

query_filter    = (&(mail=%s)(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=senderbcc))

File: /etc/postfix/ldap_recipient_bcc_maps_user.cf.

query_filter    = (&(mail=%s)(objectClass=mailUser)(accountStatus=active)(enabledService=mail)(enabledService=recipientbcc))

Add backup mx control in domain lookup file:
- For MySQL backend: /etc/postfix/mysql_virtual_mailbox_domains.cf

query       = SELECT domain FROM domain WHERE domain='%s' AND backupmx='0' AND active='1' AND expired >= NOW()

* For OpenLDAP backend: /etc/postfix/ldap_virtual_mailbox_domains.cf

query_filter    = (&(objectClass=mailDomain)(domainName=%s)(!(domainBackupMX=yes))(domainStatus=active)(enabledService=mail))

* LDAP backend only: Add group mail and alias support for openldap backend, you have to change virtual alias lookup file: /etc/postfix/ldap_virtual_alias_maps.cf.

search_base     = domainName=%d,o=domains,dc=iredmail,dc=org
scope           = sub
query_filter    = (&(mail=%s)(accountStatus=active)(enabledService=mail)(enabledService=deliver)(|(objectClass=mailList)(objectClass=mailAlias)(&(objectClass=mailUser)(enabledService=forward))))
result_attribute= mailForwardingAddress

Dovecot

mail_location setting changed in file: /etc/dovecot.conf.

mail_location = maildir:/%Lh/:INDEX=/%Lh/

and dovecot-mysql.conf (if you use MySQL as backend) should be changed too:

user_query = SELECT CONCAT(storagebasedirectory, '/', maildir) AS home, \

and dovecot-ldap.conf (if you use OpenLDAP as backend) should be changed too:

user_attrs      = =sieve_dir=/home/vmail/sieve/%Ld/%Ln/,storageBaseDirectory=home,mailMessageStore=mail=maildir:~/%$/Maildir/,mailQuota=quota_rule=*:bytes=%$

Roundcube webmail

Change global ldap address book filter in /var/www/roundcubemail-x.y.z/config/main.inc.php. It will search mail user/group/alias for you while typing mail address in recipient field.

    'filter'        => "(&(accountStatus=active)(enabledService=mail)(enabledService=deliver)(|(&(objectClass=mailList)(hasMember=yes))(objectClass=mailAlias)(objectClass=mailUser)))", // Search mail users, lists, aliases.

New settings in /var/www/roundcubemail-x.y.z/config/main.inc.php:
log_driver syslog
syslog_id roundcube syslog_facility LOG_MAIL mime_param_folding 1 identities_level 3 quota_zero_as_unlimited TRUE
LDAP backend only: Replace 'gn' by 'givenName' in global LDAP address book. (2009.03.15)

# File: /var/www/roundcubemail-x.y.z-stable/config/main.inc.php

    'search_fields' => array('mail', 'cn', 'givenName', 'sn'),  // fields to search in
    'firstname_field' => 'givenName',  // this field represents the contact's first name

Disclaimer

iRedMail-0.5.0 supports automatically adding a disclaimer to all outgoing emails with Amavisd-new + alterMIME.

Install altermime from iRedMail yum repository:
- For i386:

# yum install altermime.i386

* For x86_64:

# yum install altermime.x86_64

Create directory to store disclaimer files if not exist:

# mkdir -p /etc/postfix/disclaimer/

In /etc/amavisd.conf, add allow_disclaimers in $policy_bank{'MYNET'}:

$policy_bank{'MYNETS'} = {   # mail originating from @mynetworks
  [ ... skip other settings here ...]
  allow_disclaimers => 1,  # enables disclaimer insertion if available
};

Add disclaimer settings before the last line:

# ------------ Disclaimer Setting ---------------
$altermime = '/usr/bin/altermime';
$defang_maps_by_ccat{+CC_CATCHALL} = [ 'disclaimer' ];

# Disclaimer in plain text formart.
@altermime_args_disclaimer = qw(--disclaimer=/etc/postfix/disclaimer/_OPTION_.txt);

@disclaimer_options_bysender_maps = ({
    # Per-domain disclaimer setting: /etc/postfix/disclaimer/host1.iredmail.org.txt
    #'host1.iredmail.org' => 'host1.iredmail.org',

    # Sub-domain disclaimer setting: /etc/postfix/disclaimer/iredmail.org.txt
    #'.iredmail.org'      => 'iredmail.org',

    # Per-user disclaimer setting: /etc/postfix/disclaimer/boss.iredmail.org.txt
    #'boss@iredmail.org'  => 'boss.iredmail.org',

    # Catch-all disclaimer setting: /etc/postfix/disclaimer/default.txt
    '.' => 'default',
},);
# ------------ End Disclaimer Setting ---------------

Create an testing disclaimer file:

# echo 'Testing disclaimer.' > /etc/postfix/disclaimer/default.txt

Restart amavisd and send mail from your webmail or Outlook/Thunderbird:

# /etc/init.d/amavisd restart
