You appear to be using Sendmail and the symptoms you describe suggest you 
have not added the list's aliases to the aliases database. Usually, the 
list aliases are output when the list is created and you have to take some 
action to pass that information to the MTA. For example, with some Linux 
installations running Sendmail, you would:

1. append the aliases output by $prefix/bin/newlist to the file 
/etc/aliases or /etc/mail/aliases

2. run sendmail -bi or run make in /etc/mail/aliases
