DNS Records Required by Opensense

1. CNAME Record (New Entry)

Instructions:

  • Create a new CNAME record:

Record Type

Host/Name

Points To / FQDN / Target Value

CNAME

smart

whs.sendergen.com

2. SPF Record (Modify Existing TXT Record)

Record Type

Host/Name

Value

Example

TXT (SPF)

@ or your domain root (e.g. customer.com)

include:_spf.sendergen.com

v=spf1 include:_spf.google.com include:_spf.sendergen.com ~all

Instructions:

  • Locate your current SPF TXT record (typically begins with v=spf1).

  • The underscore in _spf.sendergen.com is critical—ensure it is not omitted.

  • Add the following include statement to the existing entry:

include:_spf.sendergen.com

Warning

Do not create a separate SPF record. There must only be one v=spf1 TXT record at the root level of each domain.
