Since you appear to be building mailman from ports/mail/mailman, do a

  cd /usr/ports/mail/mailman
  make config

And then set the MTA option to POSTFIX,

Then just

   make install

or use portupgrade or your favorite ports management tool.

Setting the POSTFIX option for building the port will build mailman  
correctly to run with the correct owner and group settings needed for  
postfix FreeBSD.

After you have reinstalled mailman with all the proper group and  
ownerships (the port Makefile really does do it correctly), then in

  cd /usr/local/mailman/bin
  ./check_perms
  ./check_perms -f
