aliaslu - lookup an address in the alias table and forward
       a message

SYNOPSIS

       aliaslu nisdomain nistable recipuser sender bounceprog

DESCRIPTION

       aliaslu looks up recipuser in the NIS  table  nistable  in
       domain  nisdomain.   recipuser  is  case-insensitive. If a
       match is found and the value  is  not  the  empty  string,
       aliaslu  calls  qmail-queue  and  passes  the  message  it
       received on stdin.  The value  may  be  a  comma-separated
       list  of  multiple addresses, but delivery to pipes (shell
       commands) or files is not supported. If the value  is  the
       empty  string,  and  recipuser  contains  no  @ character,
       aliaslu executes bounceprog recipuser sender.   Otherwise,
       everything preceding the @ character is again looked up in
       the table.  If there is still no match,  qmail-queue  will
       bounce  the message as above.  In case of temporary errors
       (Server Unavailable, etc.)  aliaslu will exit 100.
