Bounce email notification: Sender address error

Problem description

Sending an email from the Alibaba Mail web client fails with the following error:

Sender address error

Cause

Abnormal DNS resolution for your mailbox domain name prevents Alibaba Mail from sending emails. Common causes:

• The mail exchanger (MX) record is not configured correctly and does not point to the Alibaba Mail server.

• The domain name has expired.

• You changed DNS service providers and either did not configure the correct MX records with the new provider, or the new records have not yet taken effect.

Solution

Check the DNS resolution status of your mailbox domain name:

1. Log on to the Alibaba Mail console.

2. In the mailbox list, find your mailbox and click the Manage button on the right.

3. Check the Resolution Status of the mailbox and perform the corresponding action:

a. If the status is Resolution effective, sign in to the Alibaba Mail web client and send a test email to verify the issue is resolved.

b. If the status is Resolution not effective, continue with the steps below to troubleshoot.

d. If you changed your DNS service provider, verify that the correct mailbox DNS records are configured with the new provider. After the records take effect, click Check Domain Resolution or Refresh Status in the console.

If you have not changed your DNS service provider, proceed to the next step.

e. Verify that your DNS records match the following table. If they do not, update them accordingly. After the records take effect, click Check Domain Resolution or Refresh Status in the console.
