Email and Self-Managed DNS
DNS
The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. A Domain Name Service resolves queries for these names into IP addresses for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet. Records connect services like web and email to a domain name. The DNS records below are required for your Webnames email services to work. In most cases we will automatically apply these records for you. in some other cases, you may need to apply these records manually:
| TYPE | HOST NAME | DESTINATION HOST NAME | PRIORITY |
|---|---|---|---|
| MX | yourdomain.ca | smtp.webnames.ca | 10 |
| SRV | _autodiscover._tcp.yourdomain.ca | webnames.ca | 5 / 25 port 443 |
| CNAME | autoconfig.yourdomain.ca | autoconfig.webnames.ca | |
| TXT | yourdomain.ca | v=spf1 a:spf10.webnames.ca -all |
DNS records need to be applied manually in the following cases:
- A DNS provider other than Webnames is being used
- Webnames DNS Hosting is being used
DNS records are updated via one of the following, depending on your domain's configuration:
- Domains using name servers from another provider: DNS provider other than Webnames: Apply the DNS records shown above to the name servers of your DNS provider. You can determine who is providing the name servers for your domain via a WHOIS lookup.
- Domains using Webnames Website Hosting: Webnames Web Hosting: Apply the DNS records shown above the to DNS section of your Plesk Control Panel . Replace any existing MX record, and add the remaining three records.
- Domains using Webnames DNS Hosting: Webnames DNS Hosting: Apply the DNS records above below the to your DNS Admin interface. Replace any existing MX record, and add the remaining three records.
Advanced: Prior to making these DNS changes, we recommend first lowering your TTL Time to live (TTL) is a mechanism that limits the lifespan of data in a computer or network. Shorter TTLs can cause heavier loads on an authoritative nameserver, but can be useful when changing the address of critical services like Web servers or MX records, and therefore are often lowered by the DNS administrator prior to a service being moved, in order to minimize disruptions. value to 5 minutes and allowing that change to propagate. Once the new TTL Time to live (TTL) is a mechanism that limits the lifespan of data in a computer or network. Shorter TTLs can cause heavier loads on an authoritative nameserver, but can be useful when changing the address of critical services like Web servers or MX records, and therefore are often lowered by the DNS administrator prior to a service being moved, in order to minimize disruptions. value has propagated, any future DNS changes should only take 5 minutes to propagate.
Once all DNS changes have been made, propagated and verified, the TTL value can be changed back to its previous value.
