OK – so as you saw in me email a few minutes ago it looks like my new server is generally up and running. I asked a few of my co-workers to help test by sending me emails from their various personal accounts. All good except for one, this is another techy guy that runs his own email server as well (uses exim – not that it matters for this issue). His email bounced stating his domain was blacklisted at uribl.com. Here are the log entries: 2016-04-15 18:27:01 1arF0m-0002Vq-Qb H=mail-vk0-f51.google.com [209.85.213.51] X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no F=<user(a)gmail.com> rejected during MIME ACL checks: Blacklisted URL in message. (warped.com) in. See http://lookup.uribl.com. 2016-04-15 18:29:07 1arF2o-0002WS-Uo H=mail-vk0-f48.google.com [209.85.213.48] X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no F=<user(a)gmail.com> rejected during MIME ACL checks: Blacklisted URL in message. (uribl.com) in. See http://lookup.uribl.com. The first is his test email inbound. The second was him sending the reject message content. Questions: 1. Why does uribl.com blacklist their own URL in email messages (see log entry #2)? 2. Going to http://lookup.uribl.com and looking up warped.com, it is not listed! What gives? Should I be using this checking system? Thx! Helmut
