You need a new config_directory, and it needs a main.cf and master.cf file The main.cf file specifies a mail_queue_directory and data_directory that aren't shared with other Postfix instances. Both the default main.cf and the new one need to specify inet_interfaces settings that do not conflict with each other. Then you need to list the non-default config_directory in the default main.cf under "alternate_config_directories". Then it is a matter of postfix -c config_directory start postfix -c config_directory stop sendmail -C config_directory mailq -C config_directory newaliases -C config_directory etc. to talk to the new instance. A first version of a multi-instance manager will likely become available in the coming weeks. Wietse
