Domain Aliases
A domain alias lets you receive mail across multiple domain names using a single account configuration. An alias inherits all things from the target domain — including email accounts, settings, and DNS expectations.
Aliases vs. Forwarders
Domain aliases are fundamentally different from email forwarders. A forwarder is a redirection mechanism that copies mail from one address to another. A domain alias is a unified system: the alias domain becomes another name for the target domain, sharing the very same mailboxes and settings.
No duplicate accounts needed
Domain aliases share the same email accounts and settings as the primary domain. You don’t need to create separate accounts for the alias — mail to you@alias.com lands in the existing you@yourdomain.com mailbox.
Creating an Alias
Aliases are configured in the Control Panel’s Domain Pointers section at email.adastra.ad.
- Specify the source domain
Enter the new domain you want to alias. - Select the target domain
Choose the existing domain whose accounts and settings the alias will inherit. - Confirm creation
Save to activate the alias.
DNS Requirements
The new (alias) domain needs the same three DNS record types as a normal domain so that mail routes and authenticates correctly:
| Record | Value |
|---|---|
| MX records | Match the target domain’s mail servers (the mxrouting.net hostnames shown in your Control Panel). |
| SPF record | v=spf1 include:mxroute.com -all |
| DKIM record | Identical to the target domain’s DKIM record. |
Reuse the target’s records
Because an alias inherits the target domain, its DKIM record is the same as the target’s. Copy the MX, SPF and DKIM values from the target domain over to the alias domain’s DNS.
