I left most items commented out as they are the same as the default, I
only had to set mydomain, although dnsdomainname and hostname -d both
return wonkology.org.

I need TLS authentication, and found what I need in a howto:
smtp_sasl_tls_security_level = may
And I removed smtp_sasl_mechanism_filter.

Relaying does not work yet, I get a "Relay access denied (in reply to
RCPT TO command)" error. But my initial goal is reached, I can send mail
to {root,wonko}@wonkology.org. That's all I wanted.
Many many thanks kashani! Your howto is much more than I expected, it is
much appreciated. I realize that postfix is not too complicated, so I
will play more with it when I have some spare time.
