This is being looked at. Unsure why (and they don't give much info), but lists.nanog.org is only used for the list, and doesn't relay non-list emails.
I work in the email deliverability field (for honest senders); the SBL's primary design intent was catching "snowshoe" operations, that spread the spamload over multiple IP ranges and/or domains. None of that behavior can be associated with this IP; however, we have some (rare) occasions when one of our clients, sending confirmed opt-in email from a single domain and netblock winds up listed. Normally Spamhaus is quite responsive in resolving these issues.
It was showing on the CSS Blocklist, not that it makes much difference. As of this morning, it's been removed and the queue is processing down. What I see lots of (and is infuriating) is people will click "report spam" in their MUA rather than unsubscribe. Perhaps I assume to much for members on a technical list to know how to unsubscribe from a list by reading the RFC-2919 headers. I've found RBLmon to be a useful tool, but I don't think it's been updated in about 15 years and doesn't support IPv6. BTW postmaster@lists.nanog.org and admins@nanog.org are real accounts that have real people looking at them. I guess it's kinda retro in that regard :-D Thanks, -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
