Off-topic: Stef, if you read mailing lists: the MX associated with memberwebs.com is still using ORDB. You need to contact said mail administrators can tell them to stop using it, because it's returning false positives for every mail delivered to that domain: : host memberwebs.com[209.66.100.222] said: 554 Service unavailable; Client host [72.20.106.3] blocked using relays.ordb.org; ordb.org was shut down on December 18, 2006.
