Question

Digital Ocean IP range blocked by Spamhaus PBL. Anyone has any contacts?

Posted August 14, 2017 3k views
DigitalOcean

As you can see here (https://www.spamhaus.org/pbl/query/PBL1669837) the range 159.203.240.0/24 is listed on the Policy Block List (PBL) by Spamhaus which is meant to indicate that this range belongs to end-user/dial-up/cable/etc customers and is probably not meant to send emails.

However that range most definitely belongs to Digital Ocean (in fact the whole 159.203.0.0/16 does - see http://whois.domaintools.com/159.203.240.0) and has proper reverse DNS set up (as do all hosts in DO).

Does anyone have any technical contacts at Spamhaus? I guess this listing is due to some technical issue on their end, however I can’t get in touch with them (they are notoriously hard to get in touch with) and the only option I see on their site is to “remove one IP” - but I would like to tell them that the entire range is erroneously listed.

Cheers.

*I am also having the same issue. *Spamhaus is preventing from sending email addresses. I had an issue with IRedMail and decided to try with MailInABox and still experiencing the same issue. Digital Ocean needs to take care of this ASAP!!!!

Every new ipaddress I get with a new droplet is blocklisted from Spambaus

Spamhaus is not a blacklisting service therefore digitalocean is not blocked.
I got a snippet of what was on their site after some researching:
PBL listings do not prevent you sending email unless your email program is not authenticating properly when it connects to your ISP or to your company’s mail server. This can happen if you have changed something in your email program’s settings, forgotten to turn on ‘SMTP Authentication’ or if you have switched 'SMTP Authentication’ off by mistake.

    No? How about I paint a red “X” on your forehead, but tell you that it doesn’t stop you from doing anything. Go about your normal business.

    Thanks.

Hello all,

In our public community, we aim to answer open questions about anything SysAdmin, DigitalOcean and beyond. However, we make every attempt to keep personal information safe and so don’t ever access personal account information here. This means we can’t provide help with any account or billing-related issues.
