/^.*-owner\@sympaserv\.com$/ sympabounce:
/^.*\@sympaserv\.com$/       sympa:

After these are set up, run:
sudo postalias /etc/sympa/sympa_aliases
sudo postmap /etc/sympa/transport_regexp

I am getting this error when I run
root@lists:/home/ptashraf# postalias /etc/sympa/transport_regexp
postalias: warning: /etc/sympa/transport_regexp, line 1: need name:value pair
