Before you all start panicking, from the Postfix mailing list:
======================================================================
just a quick note that deliverability to domains in the .de zone
is currently limited due to dns(sec) issues at DENIC.

This also affects this mailinglist via list.sys4.de.

Best regards,

INVESTIGATING

Frankfurt am Main, 5 May 2026 – DENIC eG is currently experiencing
a disruption in its DNS service for .de domains. As a result, all
DNSSEC-signed .de domains are currently affected in their reachability.
The root cause of the disruption has not yet been fully identified.
DENIC’s technical teams are working intensively on analysis and on
restoring stable operations as quickly as possible.
Based on current information, users and operators of .de domains
may experience impairments in domain resolution. Further updates
will be provided as soon as reliable findings on the cause and
recovery are available. DENIC asks all affected parties for their
understanding. For further enquiries, DENIC can be contacted via
the usual channels.
======================================================================

SFA to do with DNSmasq.

        Cheers,
