This message means receiving server was unable to perform DNS request
for your host. Which means connectivity issue or your DNS server issue.

Best,

Have you installed the Big DNS patch?

Subject: fehcom.de having DNS problems?

Hello,

I'm sending this to the qmail list because apparently direct emails from
my servers to fehcom.de are not being accepted due to DNS issues:

2015-09-02 19:52:20.837319500 delivery 15175: deferral: Connected_to_85.25.149.179_but_sender_was_rejected./Remote_host_said:_451_DNS_temporary_failure_(#4.3.0)/

I'm not sure exactly what DNS temporary failure might be happening here,
but this message doesn't provide enough detail for me to know.

Thanks,

Andy

No, actually, it is not the same issue. That error message is being
reported by fehcom.de's mail server, not mine. Again:

2015-09-03 07:36:08.044773500 delivery 15260: deferral: Connected_to_85.25.149.179_but_sender_was_rejected./Remote_host_said:_451_DNS_temporary_failure_(#4.3.0)/

This indicates that 85.25.149.179 is reporting a DNS error on *it's*
side.

No, and I don't need the Big DNS patch. The problem is not DNS on my
end, it's a DNS error coming from the remote server.

Hi,

the provisional (and incorrect) implementations of RFC 7505 in dns.c resulted in that error.

This should be fixed since yesterday.

Don’t worry.

Best regards.

—eh.
