[BlueOnyx:24507] Re: Problem with "Accept from unresolvable domains"

[Larry Smith]

Appears the issue is:

<quote>
smtpd_helo_restrictions =
    permit_mynetworks
    permit_sasl_authenticated
    reject_invalid_helo_hostname
    reject_non_fqdn_helo_hostname
    reject_unknown_helo_hostname
</quote>

which is quaranteed to cause fails from what I can see.
