In pictures (-> is same host, ---> between hosts): dual stack IPv6 only mta2 or mta3 ---> mda -> mailman mta2 <--- mda <- mailman On the MTA relay_map is used. On the MDA relayhost is used. So all mail in or out goes goes by way of one of the dual stack hosts. It works. Really. :-) Look at the Received headers. Cutover from an old mailman host to new just means modifying relay_map file on the mta (old to none, then none to new, where none is a fqdn with no host so that mail fails and gets spooled, then sent after the second change). If the mda/mailman host is also running apache, then I need IPv4 for people who don't have IPv6 to get to the web interface. No one seems to use (or want) the archives on this host. Subscriptions are from a database populated by other means. So the web interface is currently unused (but take it away and someone is bound to try to use it).
