Amsterdam 1 Server (AMS1) UCEPROTECTL3 Spam Blacklisting

I don’t actually use my droplet as a mail server but at some point I was using and did registered my IP for periodic spam blacklist check. Couple of days ago, I have received UCEPROTECTL3 blacklisted warning. Tried to remove it. I’ve been warned that I was not allowed to remove my IP from their list. Because my IP wasn’t blacklisted but my IP range was.

At this point I don’t know even if this affects mail traffic or not. Didn’t even try. But I am planning turning my droplet to some sort of showcase in couple of months and I need every capability of this droplets can offer.

My questions would be: What should I expect from this blacklisting? Does anyone from this server having any issues regarding mail traffic? Is moving my droplet to another server a solution (since this may be a temporary occurrence)?

I would recommend contacting our support team. We work diligently to keep our IP ranges off of blacklists and they should be able to assist you with resolving this by identifying the IP in that range that is responsible and taking action.

I would recommend to use a service like mandrillapp or mailgun to take care of your emails, that would be a quicker and better solution.

Same problem here. My email messages are being blocked by Gmail et al for being included in this list.

In attempting to set up a mail server, and finally getting it working mostly. I discovered this same problem. My test email was received on some external email addresses, but Yahoo put a nice “X-YahooFilteredBulk” header tag into the received email and threw it into the spam folder.

This led me to http://www.uceprotect.net/en/rblcheck.php, which led to http://www.whitelisted.org/. Our IP is not involved in any of the reported incidents, and so I suppose if we had $21/month (or $100+ per 2 years) to spare, we could get whitelisted, and the problem would likely go away, but I do not know.

I’ll be contacting support shortly, as a result of RyanPQ’s suggestion.

Just as an update I see that my droplet IP is, as of now (August 2019), part of a new UCEPROTECT3 blacklist that covers a large piece of DO IP space.

It’s nothing that I’ve done wrong and nothing that anyone in the IP space close to me is guilty of, but the UCEPROTECT website claims that there are a lot of DO droplets sending spam at the moment.

I’ve put a support ticket in to ask what DO are able to do about this - I’d encourage others inconvenienced to do the same.

Just got the notification from monitoring service that it’s removed from the blacklist.

I am getting blacklisted from this entity too. Most of our emails don’t reach do to this.

Hello all,

Mail providers should not check against UCEPROTECT’s blacklist database and even if the IP address is listed there you should not have any issues with the mail delivery. The third-party will also charge for the IP removal from their site.

If you have any bounce back messages you can paste them here so we can check them. You can also reach out to our amazing support team and they can assist you as well.

If you’re just attempting to send outgoing mail from the server, I strongly recommend using a service like Sendgrid or Mandrill. They both offer free tiers. If that’s not an option, you can recreate your droplet in order to pick up a new IP address. The system attempts to reserve the IP for you if you create a new droplet with the same name as the old one. So in order to ensure that you receive a new IP, create the new one before destroying the old one.

Regarding the blacklist itself, I could suggest contacting the DigitalOcean support team directly for further assistance.

As a side note, here is an interesting read on why you may not want to run your own mail server but rather use an SMTP provider:

When setting up a web site or application under your own domain, it is likely that you will also want a mail server to handle the domain's incoming and outgoing email. While it is possible to run your own mail server, it is often not the best option for a variety of reasons. This guide will cover many of the reasons that you may not want to run your own mail server, and offer a few alternatives.
