 expand_alias(1)                                             expand_alias(1)




 NAME    [Toc]    [Back]
      expand_alias - recursively expands the sendmail aliases

 SYNOPSIS    [Toc]    [Back]
      expand_alias [-rmax_recursion] [-t] [-tt] alias

 DESCRIPTION    [Toc]    [Back]
      Expand_alias is a shell script that recursively expands the sendmail
      aliases.  Through use of telnet host 25 and the expn command, each
      alias is recursively expanded into its destination(s).  Indentation is
      used to show each level of recursion.  Because of the recursive use of
      telnet, expand_alias is slow.  If the local telnet cannot directly
      connect to a remote system, due to a firewall configuration,
      expand_alias will not be able to succeed. If the local telnet is to
      transparently connect across the firewall, expand_alias will be able
      to contact sendmail daemons outside the firewall, allowing the alias
      to be more fully expanded.  (For example, some local telnet clients
      use a socksd located on the firewall to permit the local telnet client
      to transparently connect to Internet hosts. If the local default
      telnet uses a socksd in such a manner, expand_alias will use that
      telnet functionality to more fully expand an alias.)

      max_recursion defaults to 10.  After max_recursion expansions, no
      further expansion is attempted.

      If -t is specified, only the terminal aliases will be displayed.

      -tt is similar to -t except that if a terminal line has a pipe, its
      printing is suppressed and the previous level of expansion is printed
      instead.

 EXAMPLES    [Toc]    [Back]
      expand_alias root

      expand_alias root@cat

      expand_alias root@cat.cup.hp.com

      expand_alias root@cup.hp.com
