How to hide the -outgoing address?

Hi all,
I'm news to majordomo so forgive me if this is a stupid question.
I'm setting up a managed list with majordomo which seems to work good,
but there is one thing that i don't get arround: i have the following
in my alias-file:
test:    "| /usr/lib/majordomo/wrapper resend -l test test-outgoing"
test-outgoing: :include:/var/lib/majordomo/lists/test
so, if the users post to test everything is good, but if they post to
test-outgoing all the majordomomanagement will be bypassed. this
wouldn't be a problem if users wouldn't know about test-outgoing, but
majordomo puts this address in some mail-headers when sending mail to
the list.
So, how can i either get around the test-outgoing address completely
or tell md not to mention this address?

Majordomo 1.94.5
Perl v5.8.1
OS SuSE 9.0 x86
Mailer is Postfix 

Thanks
