If $alias_maps of postfix is properly set up, makefml automatically prepare fml and postfix configuration for the new ML. See for the detail of postfix configuration. makefml do not update system aliases (e.g. /etc/mail/aliases), but updates only alias file $ml_home_prefix/etc/mail/aliases file, which is used only for fml. makefml rebuilds aliases.db automatically, too. $ml_home_prefix/etc/mail/aliases has the following entry for elena@home.fml.org ML. ### <ALIASES elena@home.fml.org ML> ### # address for post elena: :include:/var/spool/ml/elena/include owner-elena: fukachan # address for command elena-ctl: :include:/var/spool/ml/elena/include-ctl owner-elena-ctl: fukachan # maintainer elena-request: elena-admin elena-admin: fukachan, elena-error # error analyzer elena-error: :include:/var/spool/ml/elena/include-error owner-elena-error: fukachan ### </ALIASES elena@home.fml.org ML> ### In the case of virtual domain, $ml_home_prefix varies with $virtual_maps.
