nether.net open-relay home
What we are doing:
Any host that sends e-mail to an invalid username @ puck.nether.net or @nether.net is tested to insure that it is not an open-relay. due to the proliferation of spam due to open-relays we have found this to be a necessity.
we perform the same tests that are performed if you were to telnet to mail-abuse.org from your mail server. You can check those tests by doing so. It does a reverse-connect to your ip and tests it for a various set of ways that one can send e-mail that would turn out to pass through anti-relaying features.
if you have questions about the testing we are doing feel free to write us an e-mail.
Why was I directed here?
Query the open relay db
stats on # of relays, hosts, etc..
I fixed my relay, please remove me
I want to run my own tester
I want to tag messages with a header that says it's spam
Can I use your list on my own mail server?
