"fmladdr" (/usr/local/bin/fmladdr) lists up all users on this host. It shows users defined in /etc/passwd and aliases defined in Postfix.
The difference between "fmladdr" and "fmlalias" is whether it contains users defined at /etc/passwd or not. "fmladdr" contains it but "fmlalias" not. "fmlalias" lists up all users defined at aliases.
