    Header from a thread subscription email: 
    Received: from 89.234.66.109 (unknown [89.234.66.100])
	by smtp.boards.ie (Postfix) with SMTP id 3AA33FF43D5
	for <boardsuser@domain>; Fri,  5 Sep 2008 00:32:14 +0100 (IST)

    This header triggers several SpamAssassin rules:
    RCVD_NUMERIC_HELO
    RDNS_NONE
    TVD_RCVD_IP4

    Can this be fixed please? These extra rule hits are contributing to some boards.ie emails being flagged as spam by SpamAssassin.

    89.234.66.100 *should* HELO/EHLO with a hostname or FQDN, not an IP address (which is not even the correct IP address)
    89.234.66.109 *should* be able to resolve 89.234.66.100 to 'ip-89-234-66-100.dedi.digiweb.ie' - it looks like this is failing as it shows in the header as 'unknown'. Note: Your Postfix install may be using its own copies of 'hosts' and 'resolv.conf' at /var/spool/postfix/etc
