<p>Hello All,</p>
<p>Spamhaus is making some changes in their policy enforcement, from
their website:<br>
<br>
<i>Are you currently using the Spamhaus Project\u2019s DNS Blocklists
(DNSBLs)? Do you access them via the Public Mirrors, for
example, query \u201csbl.spamhaus.org\u201d or \u201czen.spamhaus.org\u201d? Do you
use Cloudflare\u2019s DNS? If you\u2019ve answered \u201cyes\u201d to all three of
those questions, you need to make some changes to your email
infrastructure. These changes are quick and easy to make, but if
you fail to make them, you could find that at some point in
2022, all or none of your email is blocked!</i><i><br>
</i><br>
So if you use Cloudflare DNS and have configured Zimbra to use the
public Spamhaus mirrors, you need to make some changes. Please
note that even if you do not use Cloudflare there are other cases
where you also cannot use \u201csbl.spamhaus.org\u201d or \u201czen.spamhaus.org\u201d
anymore.<br>
