Make sure that the postconf in your $PATH matches where the Postfix
config directory really is.  Depending on which distro you're actually
using, it might be somewhere like /usr/local/etc/postfix/ or something

If locate's db is up to date then there's a good chance that running
"locate" will answer this for you (or confirm you really don't
have a Postfix config file; but if that were true then you'd have much
bigger problems with launching Postfix).

Anyway, assuming postconf is not loading the right file, but the
config file exists, then you can just edit the file directly
((possibly via sudoedit) to add your relayhost config line.  Then
follow it with:

    $ sudo postfix reload
