problem with alias expansion

[Cheryl Bien <bien@antares.aero.org>]

We're running zmailer-2.2.1-mea-940322.

We have aliases that look like this:

	testa: bien
	testb: bien
	testc: bien
	testall: testa, testb, testc
	bien: bien@antares.aero.org

When zmailer expands the aliases, it doesn't expand it correctly -- it
misses the expansion for *one* of the aliases:

	(#54) telnet mail 25
	Trying 130.221.16.2 ...
	Connected to mail.aero.org.
	Escape character is '^]'.
	220 aero.org Server ESMTP ready at Wed, 1 Jun 1994 20:14:10 -0700
	expn testa
	250 smtp delivery to antares.aero.org for <bien@antares.aero.org>
	expn testb
	250 smtp delivery to antares.aero.org for <bien@antares.aero.org>
	expn testc
	250 smtp delivery to antares.aero.org for <bien@antares.aero.org>
	expn testall
	250-smtp delivery to antares.aero.org for <bien@antares.aero.org>
==>	250 Cheryl Bien <bien>
	quit
	221 aero.org Out
	Connection closed by foreign host.
	(#55) 

==> It doesn't see that this should be bien@antares.aero.org and tries
==> to deliver it locally.

The same thing happens for two aliases as in:

	testa: bien
	testb: bien
	testall: testa, testb
	bien: bien@antares.aero.org

"expn testall" gives the same results as above (one expanded alias and 
one it thinks is local).

Has anyone run into this problem before?  Does anyone have a fix?
