Checking of my IP (217.182.79.147) at http://www.uceprotect.net/en/rblcheck.php gives the info that it has been listed because there were 1868 spamming IPs from within this ASN last 7 days while their threshold for level 3 listing is 717. My question is: how widely is this BL (UCEPROTECT level 3) used? Do I have to worry about deliverability? Their page tells me to ask my provider to fix the issue, which I will do, but... it's OVH, so you know... I also find it quite impudent that the people who run UCEPROTECT offer the whitelisting option (ips.whitelisted.org), but request payment for it... If you provide access to blacklist for free, you should whitelist for free as well.On one hand, UCEPROTECT is relatively aggressive, and their unlisting policy is at least questionable. However, running a blacklist incurs costs in terms of server time and admin time, so if they provide access for free, how should they recover their costs? On the other hand - this is OVH! They are huge, and they don't seem to have a working abuse desk (at least I never got any reaction to abuse reports I sent there, and I've most likely send hundreds). This means they are an attractive spammer haven, and the number of persistent spammers in their network is significant. In light of this, UCEPROTECT taking whitelisting fees from users of cheap providers that cut their costs by not paying an abuse team or by making a profit from spammer hosting looks not so unreasonable after all. I do not condone their practice, though. On the mail systems that I run, mails from this AS would be rejected with a temporary error code until I see sufficient reason to whitelist the IP, which may take a day or more. There's a saying in german "Billig muss man sich leisten können" - "You have to be able to afford buying cheaply".
I agree with what you said. That said, those who use UCEPROTECT above level 1 to unconditionally block mails deserve to lose mails.
