Hello,
I just got an unsolicited e-mail from the domain 'bbbmail.com', which is hosted at '46.235.78.1'.
'46.235.78.1' does not resolve to a host name, therefore 'bbbmail.com' is not a FQDN.
I have 'reject_non_fqdn_helo_hostname' enabled; how did this unsolicited e-mail get through?
Regards, Nikolas Kallis
