    It seems that I could make this thing working. We have only one
    domain, so there is no need of transport maps (I think so, please
    correct me if I'm wrong). I just added a relay_domains=my.domain and a
    relayhost=[real.mail.server.ip], it seems that it's working correctly.

    Does accepting mail for count as open relaying?

    Should I set up the postmaster and abuse addresses locally, since my
    real mail server actually does have these accounts?
