Changing the DNS server that ASSP uses did the trick. I recently moved it from OpenDNS back to my ISP because of your post concerning Spamhaus and OpenDNS/GoogleDNS. So it looks like the issue is my ISP's DNS. But I'm not sure I understand what impact my DNS has on how DNSBL works. I thought all that happened was the IP address for the sending SMTP server was sent to the RBL service and checked against their database to see if it was a good or bad IP. How does my DNS server play a role in this? ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ Assp-test mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/assp-test
