Thanks v. much.

Unfortunately there is a configuration mismatch which occurs if the 
instructions given by mailman are followed. After creating a list mailman 
suggests that aliases are added to /etc/aliases.  If those aliases are copied 
as instructed my experience is the group mismatch error reported in this 
thread. The aliases are in fact generated when mailmans bin/genaliases command 
is run.

Judging from the results of google searches I seem not to be the only one who 
has experienced this result after installing mailman from the ports setting 
the mail options for postfix.

Thanks for getting back to me.. maybe a warning needs to be added to the
