ERROR : (r0:55248) Query failed: DNS server error: server failure

we try to connect this domain " skywaytour.com " for email delivery, we’re getting the below error message,

ERROR : (r0:55248) Query failed: DNS server error: server failure

I’m not sure what exactly you’re doing or why you’re getting that error message, but…

The domain’s MX records are mostly wrong. In particular, they have “lgoogle.com” instead of “l.google.com”.

Fortunately, lgoogle.com seems to be controlled by Google, but it doesn’t resolve properly, which might be why you get the “server failure” error.

Additionally, domains are only supposed to have 5 G Suite MX records, but this one has 7 (3 of them misspelled). Google changed the MX records. The old and new ones still work, but this domain has a combination of the two for some reason. It’s probably mostly harmless, but should get cleaned up.

Also, it has those mailhostbox.com MX records. I don’t know if that’s on purpose, in case Google has an outage, or what.
