I'm currently having an issue with exim4. Some mail isn't delivered. I found this in my rejected log.

2012-06-21 10:11:47 H=bart (bart.*.com) [] F=<info@****.com> rejected RCPT <>: all relevant MX records point to non-existent hosts

Is this an issue with my server or rather with the recepients server?

The DNS server of the recipient domain isn't configured properly. You can find more information about the problem on the Exim wiki.

Edit: Now when I have the recipient domain, here's some updated information. The MX servers for the domain are:

$ dig +short mx

The problem is that they don't have proper A records:

$ dig | grep NXDOMAIN
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 60414

Above I pasted only the MX with lowest priority for brevity, but all of them doesn't have A records.

When I fetch the dns records for the host I get valid hostnames.; <<>> DiG 9.7.3 <<>> mx ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52851 ;; flags: qr rd ra; QUERY: 1, ANSWER: 4, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ; IN MX ;; ANSWER SECTION: 600 IN MX 8 600 IN MX 10 600 IN MX 7 600 IN MX 9 – W.

You get valid hostnames for the MX records, but neither of them resolves properly - they don't have A records in the DNS. – Vladimir Blaskov Jun 21 '12 at 8:58
I edited my answer above with some more information added. – Vladimir Blaskov Jun 21 '12 at 9:02
