domain 'spamcop.net' matches the DNS Black List

Recommended Posts

Tried to send an email to someone. It's someone asking a question

about TCP and I was just answering about the TCP timeout value.

Error message came back saying this :

ERROR: Your message could not be delivered.

The mail server generated the following error message:

The following message to <woods[at]weird.com> was undeliverable.

The reason for the problem:

5.1.0 - Unknown address error 550-"5.1.8 rejecting sender address 'gilbert.fernandes[at]spamcop.net'.\n5.1.8 The domain 'spamcop.net' matches the DNS Black List entry:\n5.1.8 \n5.1.8 \tspamcop.net.postmaster.rfc-ignorant.org\tIN A\t127.0.0.3\n5.1.8 \n5.1.8 Please note the following additional important information:\n5.1.8 \n5.1.8 Not supporting postmaster[at]spamcop.net\n5.1.8 \n5.1.8 Please forward this message in its entirety to your own LOCAL\n5.1.8 <postmaster> and ask them to help you to resolve this problem.\n5.1.8 \n5.1.8 Postmaster[at][]: If you require assistance in\n5.1.8 resolving this issue please contact <postmaster[at]most.weird.com>.\n5.1.8 You must include your IP number, given above, in order to receive\n5.1.8 any useful help. The best way do do this would be to forward this\n5.1.8 entire status response."

Timeout for TCP is about 5 days.


unzip ; strip ; touch ; grep ; finger ; mount ; fsck ; more ; yes ;

fsck ; umount ; sleep

What's the problem exactly ?

Known issue, ancient news .... the arguement is that this particulr BL makes the call due to a robotic query made (and of course other helpful requests <g>) to the Postmaster address. What rfc-ignorant wants is a human answer. What SpamCop.net offers is a robotic reply with several addresses to actually make contact, based on the subject matter. this doesn't fit the "rules" so rfc-ignorant has SpamCop.net listed as it states in the message you provided .... Not supporting postmaster[at]spamcop.net ... much discussed, atgued by a few, but ... that BL is the rfc-ignorant BL ... its requirements are documented.

If you want to argue with someone, the most chance of changing anything would probably be the recipient's ISP, but ... once again, what tools that ISP chooses to use to try to control their incoming e-mail is their call ...

There are BLs out there that list things based on country, IP Block, just because ... most of them identify what they block and why, most have removal instructions ... but again, they are just lists created and managed by someone for their purposes .. use of them by others is done at their own risk ....

I will find another way. Otherwise, someone else will help him probably over his TCP matter.

Thank you.

All that is required for a domain to stay off the postmaster.rfc-ignorant.org list is that it "be clear that the e-mail that generated the auto-ack will in fact be dealt with" per postmaster.rfc-ignorant.org listing policy, and all that is required for a domain to stay off the abuse.rfc-ignorant.org list is that it "must acknowledge that the complaint will be acted upon, as submitted to the main abuse[at]domain address" per abuse.rfc-ignorant.org listing policy.

The sample auto-responses cited by listings http://www.rfc-ignorant.org/tools/detail.p...able=postmaster and http://www.rfc-ignorant.org/tools/detail.p...995&table=abuse linked from http://www.rfc-ignorant.org/tools/lookup.p...mcop.net&full=1 do not make it clear that the email sent to postmaster or abuse at spamcop.net "will in fact be dealt with" or "acknowledge that the complaint will be acted upon", in violation of RFC2821/4.5.1 and RFC2142, among others. I suggest that those auto-responses be changed to make that clear, or be eliminated altogether.

Also, why should spamcop.net be using auto-responders when it frowns on their use by others via http://www.spamcop.net/fom-serve/cache/329.html#responder?
