NAME
expand_alias - recursively expands the sendmail aliases
SYNOPSIS
expand_alias [-rmax_recursion][
-t][-tt] alias
DESCRIPTION
Expand_alias is a shell script that recursively expands the
sendmail aliases. Through use of tel-
net host 25
and the expn command, each alias is recursively expanded into its destination(s). Inden-
tation 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.

expand_alias root
expand_alias root@cat
expand_alias [e-mail]
