eugeni.torproject.org got on barracuda blacklist
Nick from Calyx tried to mail an @torproject.org address, and it failed because
Sep 18 20:00:12 eugeni/eugeni postfix/smtpd: NOQUEUE: reject: RCPT from mx2-nyc.calyxinstitute.org[184.108.40.206]: 450 4.1.7 <email@example.com>: Sender address rejected: unverified address: host mx2-nyc.calyxinstitute.org[220.127.116.11] said: 554 5.7.1 Service unavailable; Client host [18.104.22.168] blocked using b.barracudacentral.org; http://www.barracudanetworks.com/reputation/?pr=1&ip=22.214.171.124 (in reply to RCPT TO command); from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<mx2-nyc.calyxinstitute.org>
It looks like eugeni in general is failing to deliver mail to anybody who uses barracuda to decide who is in their walled garden and who isn't. (And it is failing to accept the mail too, because our postfix doesn't accept mail from people who aren't willing to accept mail from us -- "if you can't receive a reply, you're probably a spammer".)
I went to the "take me off your blacklist" url and filled it out:
This is the mailserver for the torproject.org domain, which has hundreds of users and hosts mailing lists for hundreds of thousands of people. I don't know how we got on the barracuda blacklist, but apparently we did. Maybe there is a way for you to confirm that yes, this mailserver handles many thousands of good mails, so it should be acceptable?
I'm not optimistic, since the web form says "Removal requests are typically investigated and processed within 12 hours of submission if provided with a valid explanation." and I don't know what counts as a valid explanation but "your stupid blacklisting thing blacklisted us and so it's broken" might or might not count. We'll see!
