Hi Lyle and Al,

Thanks for your responses to my query.

I have signed up for SpamHaus' DQS service and tested my e-mail config
via their test website and all is good to go!

Even if this wasn't happening, you should still go sign up for DQS.

Re: [mailop] Spamhaus and Vultr

[Lyle Giese via mailop]

Based on reading Spamhaus's page(referenced below), they will slowly 
block ALL Vultr ip address space from using the Spamhaus public 
mirrors.  Doesn't matter what the reverse IP address is.


But signing up for Spamhaus DQS free service, you merely change your 
configuration after getting a free DQS key from Spamhaus.


If you are querying their zen database, you have configured queries to 
use 'zen.spamhaus.org'. You change that to 
'your_DQS_key.zen.dq.spamhaus.net'

Hi mailop,

I noticed that Spamhaus has posted a notice that after May 22nd, 
people and/or businesses making use of Vultr for their infrastructure 
will need to transition to a different way of querying the 
blocklists[1].  The post mentions that Vultr’s default reverse IP 
assignment masks who is querying the blocklists.


In my scenario, I have my own recursive, validating resolver running 
on my mail server on a Vultr instance and it has a reverse DNS name 
that is not the default one that Vultr assigns and I query: 
zen.spamhaus.org.


Do I still need to make changes ?

I am uncertain from the blog posting if this refers to people making 
use of the resolver that Vultr provides or if it extends to all of 
Vultr’s IP space (ie. all cloud instances).


Thanks,

- J
