DNS
Hyvor Relay comes with a DNS server that handles DNS queries for the instance domain and its subdomains. On each Hyvor Relay server, the DNS server listens on port 53 for UDP connections.
Default Records
The following DNS records are handled by default:
- Forward A records for each IP address
smtp1.<instance-domain>→x.x.x.x - MX record for the instance domain
<instance-domain>→mx.<instance-domain> - A records for the MX domain
mx.<instance-domain>→x.x.x.x - SPF (TXT) record for the instance domain
<instance-domain>→v=spf1 ... - DKIM (TXT) record for the instance domain
default._domainkey.<instance-domain>→v=DKIM1 ...
Custom Records
In addition to the default records, you can add custom DNS records in Sudo → Settings → DNS → Custom DNS Records. You can add A, AAAA, CNAME, MX, and TXT records for the instance domain and its subdomains here.
