aliaslookup - Look up mail aliases
aliaslookup [-m module] [address...]
aliaslookup is a command line diagnostic tool that searches the Courier's mail alias database and shows the aliases for the given address, the actual mail accounts the given address is aliased to. Mail addressed to address will be delivered to the aliased addresses instead. The optional module is rarely needed. See makealiases(8) for more information.
