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). 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 ®rewall con®guration, expand_alias will not be able to succeed. If the local telnet is to transparently connect across the ®rewall, expand_alias will be able to contact sendmail daemons outside the ®rewall, allowing the alias to be more fully expanded. (For example, some local telnet clients use a socksd located on the ®rewall 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 -tis speci®ed, only the terminal aliases will be displayed.

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

EXAMPLES

expand_alias root expand_alias root@cat expand_alias root@cat.cup.hp.com expand_alias root@cup.hp.com
