I'd heard that, but I haven't had a problem with my Nanode on IPv4.
I *did* have a problem with IPv6. I was getting a lot of bounces because of course you have to pay for a /64 which I don't, and at least one RBL blacklists the whole /64 if they're mad at any of them.
I've also had a problem with Microsoft, which randomly blacklists me. I don't have any mailflows where I depend on sub-hour delivery, and so far I've always had the block cleared by their automated system within 15 minutes. That's good enough for me, and I don't know if it's related to Linode. I've heard that it happens to other people but I don't know who their ISP is.
- Don’t have a bunch of mailing list members on RoadRunner.com/Spectrum because they’ll classify any attempt to send an email to 20+ people on there as “flooding” and bounce every to some but not all those people.
Don't you love those "friends don't let friends" service providers?
