Hi, If you haven't already seen the announcement, you may be interested to know that Spamhaus are trialling a DKIM based domain reputation service - the DWL. It's being tried alongside an IP address based whitelist, the SWL.
<http://www.spamhauswhitelist.com/en/usage.html> To get on to the DWL, you have to be using DKIM, you have to get an invitation from someone already on the whitelist, and you must not already be on a Spamhaus blocklist. -- Ian Eiloart IT Services, University of Sussex 01273-873148 x3148 For new support requests, see http://www.sussex.ac.uk/its/help/ _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
