Sending mail via IPv6

Net30Hosting

. UCE Protect does not blacklist emails sent via IPv6. All of our OVHcloud services come with at least a single IPv6 address that you can configure. All major email providers now support IPv6.

Ultimately, UCE Protect wants all of the newly blocked ASNs to pay for express delisting. ($502 per IP) Paying for delisting on blacklists only leads to an increase in blacklisting overall and ultimately hurts the industry.

UCE Protect claims automatically delist ASNs after 1 week, which we hope will happen but as it is outside of our control, we cannot provide any guarantees regarding this.

I have had an IPv4 for nearly 3 years that I had never used and it too was black listed. Hence my leaving OVH, and discovering Enhanced in the process and ditched cpanel for this.

i don't know anyone who uses UCE Protect to block any mail.

But there is no much we can do, since they block entire ASN or big ranges of IP, even if is not your fault. is more like your provider (the DC or the IP provider) is not taking actions agains't spam abuse (not your fault).

Unfortunately you'll find the vast majority of cloud providers have their entire ranges blocked by UCE Protect. There's very little you can do about this, and if you don't have your own IP space it's why realistically you're best using a smart host with a service that can provide SMTP via clean IP addresses. So for example SpamExperts, MailChannels. Mail.baby. Some people do use Amazon SES and it is good for the most part, however, it isn't suitable for a shared hosting environment because domains need to be validated before being able to send through SES.

We currently use Mail.baby and it is very good despite the fact that from time to time some outbound emails are detected as SPAM.
BTW it would be interesting to have some kind of Amazon SES integration that could automate the domain validation process that otherwise would have to be made manually for each domain added to the control panel.
