Postfix configuration¶
This page mentions all Postfix configuration parameters, which have to be
modified and/or added in/to the Postfix main.cf
.
main.cf¶
Add or replace the following configuration parameters in the global Postfix
configuration file.
The Postfix PostgreSQL client configuration files (pgsql-*.cf
)
mentioned below will be created when vmm will be installed.
sql = pgsql:${config_directory}/
proxysql = proxy:${sql}
# relocated users from the database
#relocated_maps = ${proxysql}pgsql-relocated_maps.cf
# transport settings from our database
transport_maps = ${proxysql}pgsql-transport_maps.cf
# virtual domains, mailboxes and aliases
virtual_mailbox_domains = ${proxysql}pgsql-virtual_mailbox_domains.cf
virtual_alias_maps = ${proxysql}pgsql-virtual_alias_maps.cf
virtual_minimum_uid = 70000
virtual_uid_maps = ${sql}pgsql-virtual_uid_maps.cf
virtual_gid_maps = ${sql}pgsql-virtual_gid_maps.cf
virtual_mailbox_base = /
virtual_mailbox_maps = ${proxysql}pgsql-virtual_mailbox_maps.cf
# dovecot LDA (only recommended with Dovecot v1.x)
#dovecot_destination_recipient_limit = 1
#virtual_transport = dovecot:
# dovecot lmtp (requires Dovecot ≧ v2.0.0)
virtual_transport = lmtp:unix:private/dovecot-lmtp
# dovecot SASL
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/dovecot-auth
smtpd_sasl_auth_enable = yes
# Keep smtpd_sasl_local_domain identical to Dovecot's auth_default_realm:
# empty. Both are empty by default. Let it commented out.
# Read more at: http://wiki2.dovecot.org/Authentication/Mechanisms/DigestMD5
#smtpd_sasl_local_domain =
smtpd_sasl_security_options = noplaintext, noanonymous
#broken_sasl_auth_clients = yes
smtpd_recipient_restrictions =
permit_mynetworks
permit_sasl_authenticated
reject_unauth_destination
master.cf¶
Note
This step is only necessary if you are still using Dovecot v1.x
Add the service dovecot to Postfix’s master process configuration file. Append this lines:
dovecot unix - n n - - pipe
flags=DORhu user=nobody argv=/usr/local/lib/dovecot/deliver -f ${sender}
-d ${user}@${nexthop} -n -m ${extension}
The command of the argv attribute points to the root SETUID copy of deliver. For more details about the flags used above see: pipe(8). All other arguments are explained in the Dovecot LDA documentation.
Using Dovecot’s LMTP¶
In order to use Dovecot’s LMTP as virtual_transport with Postfix make sure you have have:
- lmtp in your protocols setting (dovecot.conf)
- configured a lmtp listener: service lmtp {} (conf.d/10-master.conf)
- set lmtp:unix:private/dovecot-lmtp as the domain.transport in your
vmm.cfg
.
If you want to switch the transport of existing domains and/or accounts, you can use the subcommands domaintransport and usertransport.
