Custom Domain Records
A Custom Return Path (CRP) must be configured as a dedicated subdomain of the domain you want to send email from.
For example, if you want to send email from: xxxxxxxx@yourdomain.com
your CRP must be a subdomain of yourdomain.com, such as: bouncevx.yourdomain.com
Important: The CRP subdomain must be dedicated exclusively to this service. It must not be used for any other purpose or with any other email or service provider.
Placeholders Used Below
The DNS records below contain placeholders. Please replace them with your own values before creating the records. The curly braces should be removed.

1. Custom Return Path DNS Record
This CNAME record configures the return path for your Vuture instance. It also enables the associated SPF and MX configuration.
|
Field
|
Value
|
|
Record Host
|
{crp-subdomain}
|
|
Record Type
|
CNAME
|
|
Record Value
|
{instanceID}.vx-email.com
|
Example:
bouncevx.yourdomain.com CNAME 123.vx-email.com
2. DKIM DNS Records
To enable DKIM authentication, add the following two CNAME records to your public DNS.
Two DKIM records are required so that Vuture can rotate DKIM keys when needed.
DKIM Record 1
|
Field
|
Value
|
|
Record Host
|
vx._domainkey.{crp-subdomain}
|
|
Record Type
|
CNAME
|
|
Record Value
|
{crp-subdomain}.vuturedkim.com
|
DKIM Record 2
|
Field
|
Value
|
|
Record Host
|
vx1._domainkey.{crp-subdomain}
|
|
Record Type
|
CNAME
|
|
Record Value
|
{crp-subdomain}.1.vuturedkim.com
|
3. DMARC DNS Record
DMARC is required to meet current email authentication standards.
To begin with no impact on mail delivery, you can use a monitoring-only policy by setting the DMARC policy to p=none.
|
Field
|
Value
|
|
Record Host
|
_dmarc.{root-domain}
|
|
Record Type
|
TXT
|
|
Record Value
|
v=DMARC1; p=none
|
Example:
_dmarc.yourdomain.com TXT "v=DMARC1; p=none"
Do not use adkim=s or aspf=s in your DMARC record, as this can cause significant delivery issues for your Vuture mailings. They should both be set to relaxed alignment mode - adkim=r and aspf=r
Important DMARC Guidance
If you want to use a stricter DMARC policy, such as p=quarantine or p=reject, or if you want to collect and analyse DMARC reports, we recommend consulting a specialist DMARC provider.
Incorrectly applying a stricter DMARC policy can cause significant delivery issues across all email streams using your domain.
You may already have a DMARC record in place on your root domain, if so, you may not need to do anything, please speak with your IT/Network team.
