Do you by chance know by heart whether postfix (and other MTAs) use
/etc/mailname to qualify recipient addresses? I.e. does

end up at foo@<contents of /etc/mailname> or at foo@<local fqdn>?

I disagree on your evaluation, as it is not "everybody" but only every
nullmailer setup without local mail, however I strongly consider
opening this can of worms before sarge.
