    Hi Wietse

    I don't want to contradict someone who writes such brilliant software
    but I tried the suggestion below and mail started bouncing like mad.

    A quick check of the postfix website showed a potential typo ->
    reject_non_fqdn_sender (not reject_nonfqdn_sender)

    When I used this it all worked the way I expected. Perhaps it's just a
    version specific thing?

    Cheers
