Hello, we observed a strange behaviour for the domain foryoudecor.com, when trying to resolve it using bind 9.18.2, using
dig -t mx foryoudecor.com The bind log for 9.18.2 says: May 11 12:00:14 ns named[96774]: fetch: foryoudecor.com/MX May 11 12:00:14 ns named[96774]: DNS format error from 61.129.70.40#53 resolving foryoudecor.com/MX for 193.105.105.1#27259: server sent FORMERR May 11 12:00:14 ns named[96774]: client @0x803bdcd60 193.105.105.1#27259 (foryoudecor.com): query failed (FORMERR) for foryoudecor.com/IN/MX at query.c:7657 so the domain was not resolvable. bind 9.16.28 resolves the MX for this domain. I tried to find out if it's an DNSSEC issue, using https://dnsviz.net/d/foryoudecor.com But the result looks very confusing to me. Apparently, somewhere, a DNS server 'qhm3' comes into play (yes, that's the whole dns server name!). What can I do to debug this? -- p...@opsec.eu +49 171 3101372 Now what ? -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
