Spam blacklisting is out of control
I&#x27;m dealing with this right now.<p>Both my personal domain and rsync.net are on a distinct subnet, but that subnet is <i>smaller than a &#x2F;24</i> and someone on a different subnet has, apparently, behaved badly.<p>Enter &quot;abusix&quot; ...<p>One of my engineers had an enlightening webchat with one of their engineers where we were shown the &quot;offending&quot; IP and it was explained that they have no ability to distinguish subnets (and no interest in doing so).  So if you&#x27;re not wasting an entire &#x2F;24 (we only need ~10 IPs at this location) you&#x27;re in danger of this misclassification.<p>We were also informed that our normal, business communications with paying customers should have unsubscribe notices appended to them.  Which is to say, you&#x27;re a paying customer of a service and we send you some kind of alert or critical announcement ... and it should have an unsubscribe link.<p>Unbelievable.
