Domain name configuration FAQs

Last Updated: Oct 10, 2017

Some common domain name configuration FAQs:

What are the restrictions on setting up domain names?

  • You can set up to five email sender domain names for one Alibaba Cloud account. As a best practice, we recommend that you create separate domain names for sending triggered emails and batch emails.

  • A main domain name and its sub-domain names can only be used by one Alibaba Cloud account. For example, if an Alibaba Cloud account use 123.abc.com as the sender domain name for DirectMail, no other account can use the main domain name (abc.com) or any associated sub-domain names (such as 124.abc.com) as the sender domain name.

  • As a best practice, we recommend that you use subdomain names as the sender domain names to avoid flooding the main domain name with potential exceptions when sending emails.

  • If sender addresses are created for a specific sender domain name, the associated domain name cannot be deleted. Domain names without sender addresses can be deleted.

How do I configure a domain name on DNS servers?

The following demonstrates an example scenario.

Configure domain names

Take the Asia Pacific SE1 (Singapore) region, the domain name of 718test.xxx.xyz as an example.

  1. Log on to the DirectMail console.
  2. On the left-side navigation pane, click Email Domains.
  3. Find the domain name you want to configure, and click Configure.

The domain configuration information is displayed.

Domain name resolution

Alibaba Cloud DNS

If you have registered your domain name on Alibaba Cloud Domains, go to Alibaba Cloud DNS to resolve the domain name.

  1. Log on to the Alibaba Cloud DNS console.
  2. Find the domain name you want to configure, and click Configure.
  3. Click Add Record.
  4. Add one MX record, two TXT records, and one CNAME record according to the configuration information of the domain name in the DirectMail console, and then click OK.

DNSPod

If you have registered your domain name on DNSPod, go to DNSPod to resolve the domain name.

  1. Log on to DNSPod and add the domain name.
  2. Add two TXT records, one MX record, and one CNAME record according to the configuration information of the domain name in the DirectMail console.
    • Add the TXT record for the domain name ownership validation.
    • Add the TXT record for the domain name SPF validation.
    • Add the MX record for the domain name MX resolve validation.
    • Add the CNAME record for the domain name CNAME validation.

Can a DNS record configured for a domain name be modified?

No. After the successful validation of the email sending domain, DNS records cannot be modified or deleted. Otherwise, emails may be rejected by some inbound email servers.

What can I do if a domain name validation fails?

If the domain name validation fails, check whether the domain name configuration information is correct, and valid values and indicators are submitted.

Why are domain name ownership validation, SPF validation, and MX validation required?

These validations help prevent others from registering an identical DirectMail account as yours and prevent forgery of email services provided for you by DirectMail. They also help to improve overall email delivery efficiency.

How can I set DMARC records?

DMARC records help to prevent others from forging your email sending domain name, and can detect when others are trying to forge your domain name.

If a recipient, whose MTA needs to support the DMARC protocol, receives an email from the domain name, DMARC validation is attempted. If validation fails, a report is sent to the inbox where the DMARC is set.

Set DMARC records:

  1. Make sure that the following SPF record is set:
    “v=spf1 include:spf1.dm.aliyun.com -all”.
  2. Set the following DMARC records:
    _dmarc.yourdomain.com TXT “v=DMARC1; p=quarantine; rua=mailto:dmarc_report@yourdomain.com; ruf=mailto:dmarc_report@yourdomain.com”.

Note: The inbox in the record value (dmarc_report@yourdomain.com) with the configured DMARC must be an inbox with the same main domain name as the email sending domain name.
