>/24 netblock on the second offense.
That seems excessive and abusive, I am not aware of any commercial ISP that is giving out /24 anymore. /29 is most common, I had to practically beg to get a /28 so what is the justification for banning an /24???
- marcosdumay 5y agoBlock registers don't deal with "justification". If they did, what would be Google's justification for blocking senders that send too few emails?
- pteraspidomorph 5y agoI wish I knew. I have a user google keeps blocking for spam (not even marking, outright blocking) while at the same time their reporting tool say the user doesn't send enough e-mail to google for any data to be displayed (the user's domain generates less than ten e-mails per day, many/most of which not to google).
- huhtenberg 5y ago> That seems excessive and abusive Good thing it's my own mail server then, isn't it? The practical reason is that virtually all Whois lookups of offending IPs return blocks of /24 or larger, so that's a reasonable default. Besides, as I said, this doesn't result in a "ban", just tags emails as spam and passes them through. At my scale an occasional false positive is not a big deal.
