Adding a Second Postfix Instance on one Server
Base reference: http://advosys.ca/papers/email/58-postfix-instance.html
- Add an ip address to the server (e.g. 1.2.3.4)
ip addr add 1.2.3.4/8 dev eth0 # or see /etc/network/interfaces
- Copy the /etc/postfix directory and all files
rsync -av /etc/postfix/ /data/postfix/conf
- Create an additional spool directory
mkdir /data/postfix/spool && rsync -av /var/spool/postfix/{dev,etc,lib} /data/postfix/spool/
- Create an additional data directory
mkdir /data/postfix/data; chown postfix.postfix /data/postfix/data
- Edit the config files
- /data/postfix/conf/main.cf
inet_interfaces = 1.2.3.4 smtp_bind_address = 1.2.3.4 queue_directory = /data/postfix/spool/ data_directory = /data/postfix/data/
- /etc/postfix/main.cf (default configuration file)
alternate_config_directories = /data/postfix/conf/
- use postfix-install to create missing files and set/update the permissions
postfix post-install config_directory=/data/postfix/conf/ set-permissions upgrade-configuration create-missing
- check & start
postfix -c /data/postfix/conf/ check postfix -c /data/postfix/conf/ start
