do not do full mail processing on all hosts
Right now we run postfixes listening to the world on most of our hosts because, good citizens that we are, we only run proper unix hosts, and proper unix hosts do proper mail.
Change this setup to have most hosts:
- relay all their outgoing mail via eugeni.
- have eugeni be the host that receives mail for them and processes it right then and there (i.e. add the hosts name to eugeni's mydestination).
For hosts that do process some mail (say gettor), we currently don't plan to change anything.
