Which somehow got me going .. and *they* say in turn
Your email has bounced back from the recipient
Public resolver
If you are viewing this page, you have likely sent an email that was not =
delivered to the recipient. In the resulting bounced email message you have=
found and clicked this link: https://check.spamhaus.org/returnc/pub/141.10=
1.75.8
The problem doesn=E2=80=99t relate to your email set-up.
^Good.
Why has my email not been delivered?
The problem is with the recipient=E2=80=99s email server configuratio=
n.
This is not due to an issue with your email set-up.
It is not because you are listed on one of our blocklists.=20
^That is what i wanted to know, thank you.
What do I need to do next?
If the email is urgent or essential:
Call the recipient and tell them that they have an issue with receivi=
ng emails.
Ask the recipient to urgently contact their email server administrato=
r. This page provides the information required to correct this issue: Using=
our public mirrors? Check your return codes now.
For non-urgent emails
Try and resend the email in 24 hours, allowing the recipient=E2=80=99s=
email administrators time to resolve the problem.=20
Want more technical details?
We=E2=80=99ve provided the above information for the everyday email user;=
however, if you=E2=80=99re technically minded and want to learn more, keep=
reading=E2=80=A6 Queries cannot successfully be made to the Spamhaus free =
infrastructure via public/open resolvers. This is to protect the infrastruc=
ture from abuse by large-volume queriers. If you=E2=80=99d like to take a d=
eeper dive into this, check out successfully accessing Spamhaus=E2=80=99 fr=
ee blocklists using a public DNS. Some users continue to query Spamhaus blo=
cklists via public resolvers, unaware that this means that our data does no=
t actually protect their mail stream. We have introduced an error code for =
these users to provide a clear signal that there is an issue, and that the =
mailserver configuration needs to be updated.
A free upgrade: Spamhaus DQS
To succesfully query Spamhaus via public/open resolvers, there is a FREE =
service which delivers the intelligence faster and with additional blocklis=
ts available to increase catch-rates: Spamhaus Data Query Service. Here are=
the details of how to make the change:
Sign up for the free Spamhaus Data Query Service. The same usage term=
s apply.
Make the relevant change to your server configuration. The Spamhaus T=
echnical Documentation site has full configuration details for many mail se=
rvers and anti spam solutions.=20
Alternatively, if you=E2=80=99d like to continue using the free public in=
frastructure, please ensure that your queries come from a dedicated IP with=
attributable reverse and forward DNS. Here is information on how to correc=
tly configure commonly used MTAs for use with the public mirrors.
