i have multiple nullclients with the exact (!) same main.cf. all but one show the received header as expected, e.g.:

                       ^^helo string^^  ^^dns name^^     ^^remote IP

                [...]

        Received: by host.domain.tld (Postfix, from userid 1000)
                     ^ $myhostname ^

as you can see, in the upper 'Received' header both hostnames are fully qualified and identical, which is what i would expect.

but there is one single host, which doesn't:

        Received: from host.domain.tld (host1 [10.0.0.2])
                [...]
        Received: by host.domain.tld (Postfix, from userid 1000)
                [...]

here, the second hostname is not only not fully qualified, but is also an entirely different hostname.

do you have local DNS for 10.0.0.2 range?
or, do you use dnsmasq?
