The FAQ at <http://wiki.list.org/x/4oA9> summarizes much of what we know about dealing with large ISPs. On your end, you need to be sure your sending server is properly configured. At a minimum, its IP must have an rDNS that points back to its fully qualified domain name. That name must have a DNS A record that points to the IP, and it must identify itself as that domain in HELO/EHLO. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
