Initial settings

Pro

return.SUBDOMAIN.smtps.jp is registered in the reception permission domain, and in Advanced Settings -> Envelope From domain,you can perform the rewriting settings to return.SUBDOMAIN.smtps.jp

If you want to return the bounce mail to the envelope From set by the mail relay source server, change the envelope From to the "Do not rewrite" setting.

transactional-email return.te.smtps.jp

Using your own domain

Describes how to use your own domain for the envelope From.

STEP1 : Designing your own domain

In order for Customers Mail Cloud to receive bounce emails, designing the domain used for the envelope From is required.

For example, both the header From and the envelope From use info@example.com and @example.com is the domain that operates your organization's email address. In such cases,because It is necessary to separate the reception of normal mail and bounce mail,the envelope From must be assigned a subdomain of the header From.

Before Change

Item Mail address        
header From info@example.com
envelope From without settings(uses info@example.com)

After Change

Item Mail address        
Header From info@example.com
Envelope From info@return.example.com

STEP2 : Setting the MX record

Register the receiving server in the MX record of the domain that operates the envelope From. (This operation is done on the DNS server that manages your own domain)

Standard

Server configuration name     Receiving server
sandbox sandbox.smtps.jp
transactional-email te.smtps.jp

Pro

Server configuration name        Receiving server
SUBDOMAIN SUBDOMAIN.smtps.jp

STEP3: Setting the SPF record

Specifies the SPF record provided by Customers Mail Cloud for the domain that operates the envelope From. For more about SPF record please refer to Registering the SPF.

STEP4 : Setting your own domain

There are two ways to set your own domain to the envelope From.

Sender Domain Settings

When it is necessary to set the domain of the envelope from for each header from, such as when operating DMARC, perform the 'envelope from' settings from sender domain settings.

Advanced Settings

Pro

To rewrite the envelope from of all emails sent via Customers Mail Cloud at once , operate the 'envelope from' settings from "Advanced Settings".

Rewriting the envelope from set in "Sender domain settings" has priority over the settings in "Advanced settings".

STEP5 : Receiving the bounce

destination email address info@mailform.example.com

STEP2 : MX record settings

Register the following SMTP host in the MX record at mailform.example.com which assigned as the domain of the destination email address to receive emails with Customers Mail Cloud. (This operation is done on the DNS server that manages mailform.example.com)

Standard

Server configuration name     SMTP host
sandbox sandbox.smtps.jp
transactional-email te.smtps.jp
