It enables administrators and users to enforce domain trust, recover locked accounts, and resolve inbound or outbound delivery failures using built-in diagnostic paths and self-service workflows. ## Key facts - S/MIME encryption and digital signatures support a maximum of 30 certificates per mailbox and require the AI Premium Edition. - DNS configuration changes for SPF, DKIM, and DMARC records may take up to 24 hours to propagate globally. - Accounts temporarily locked due to Too many password errors automatically unlock after 1 hour, or can be manually unlocked by a user with postmaster permissions. - QR code login via the Alibaba Mail app expires after 5 minutes. - Third-party email client configuration requires the full email address as the username, POP3 on port 995, and SMTP on port 465. - Anti-spam filtering includes a Strict mode that blocks non-whitelisted senders and an option to permanently delete spam. ## How to set up secure email communication Secure email communication in Alibaba Mail is achieved by combining domain-level authentication, sender filtering, and optional end-to-end encryption. Choose the configuration that matches your security requirements: 1. Configure DNS authentication by navigating to your DNS Settings and adding SPF, DKIM, and DMARC records using the appropriate Record Type, Host Record, and Record Value fields. This prevents domain spoofing and establishes foundational outbound trust, though changes may require up to 24 hours to take effect. 2. Manage sender filters by accessing security settings to configure Blacklist or Whitelist rules by email address, domain, or IP. You can adjust the Anti-spam Level to Strict mode to automatically block non-whitelisted senders or enable permanent deletion of identified spam. 3. Enable S/MIME encryption if your organization uses AI Premium Edition. Navigate to Settings > View more settings > Account and Security > S/MIME Settings, select Import a new certificate, upload your PKCS#12 format (.p12 or .pfx) file, and enter the certificate password. An administrator must first enable S/MIME in the domain management console. ## How to recover access to mailbox login Account recovery depends on whether you have forgotten credentials, triggered a security lockout, or prefer mobile authentication. Follow the path that matches your situation: 1. Reset forgotten credentials using the Forgot Password interface to initiate self-service recovery. Verify your identity by entering a code sent via SMS to your secure phone number or by correctly answering your pre-configured Security questions, then proceed to reset your password or security settings. 2. Unlock a locked account if your interface displays Too many password errors. Wait 1 hour for the automatic unlock, or contact an administrator with postmaster permissions to manually unlock the account via the Alibaba Mail console under Employee Accounts. 3. Use QR code login by opening the Alibaba Mail app on your mobile device, navigating to the login page, and scanning the Code scanning entry. Complete the authentication before the QR code expires in 5 minutes. ## How to resolve email sending failure issues Sending failures typically stem from DNS misconfigurations, account status restrictions, or client connection errors. Diagnose and fix the issue using these targeted steps: 1. Fix DNS and authorization errors if you receive SMTP codes like 550 or 554, or messages stating SPF check failed. Verify your SPF and MX records using the Check Domain Name Resolution tool, ensure Send to External Domains is enabled in Employee Account Management, and confirm your password meets security requirements to avoid anti-spam blocks. 2. Restore webmail access if the interface returns a 503 error or shows AccountFrozen, AccountBlocked, or AccountExpired. Verify that your CNAME record correctly points to alimail.aliyun.com, and administrators can restore access by using the Unblock or Enable functions in the console. 3. Correct client configuration when using Outlook, Foxmail, or iPhone Mail. Ensure the username is your full email address, verify that POP is enabled on port 995 and SMTP is configured on port 465, and confirm that Enable POP and Enable IMAP are activated in your mailbox settings. ## How to troubleshoot why an email was not received Missing inbound emails are usually caused by routing misconfigurations, aggressive spam filtering, or mailbox capacity limits. Resolve delivery gaps by following these checks: 1. Verify inbound routing by confirming that your domain MX record is correctly published and points to the Alibaba Mail servers. Missing or incorrect MX records will prevent external servers from routing messages to your mailbox. 2. Review spam and filter rules to ensure legitimate senders are not blocked by Blacklist rules or caught by Strict anti-spam levels. Check mailbox rules and forwarding configurations that might automatically redirect or delete incoming messages. 3. Check mailbox capacity and sync settings to verify that your mailbox has not reached its storage limit, which can cause new messages to bounce. If you use POP3, ensure that historical emails are not being removed from the server during sync, and verify that IMAP folder synchronization is functioning correctly. ## Frequently Asked Questions **Q: how do I set up secure email communication** A: Configure SPF, DKIM, and DMARC records in your DNS settings to authenticate your domain, then adjust Blacklist and Whitelist rules and Anti-spam Levels in the security console. For end-to-end encryption, import a PKCS#12 certificate via S/MIME Settings, which requires AI Premium Edition and administrator enablement. **Q: what's the best way to secure email** A: The most effective approach combines foundational DNS authentication with strict filtering. Publishing SPF, DKIM, and DMARC records prevents domain spoofing, while enabling Strict anti-spam mode and managing whitelists blocks unauthorized inbound traffic. S/MIME adds message-level encryption for high-sensitivity communications. **Q: how do I recover access to mailbox login** A: Use the Forgot Password interface to verify your identity via SMS to your secure phone number or by answering Security questions. If you have the Alibaba Mail app installed, you can also scan the Code scanning entry on the login page for quick access. **Q: what's the best way to recover mailbox access** A: Self-service recovery via SMS or security questions is the fastest method for credential loss. For accounts locked by repeated failed attempts, waiting 1 hour triggers an automatic unlock, or an administrator with postmaster permissions can manually unlock the account through the Alibaba Mail console. **Q: how do I resolve email sending failure issues** A: Start by checking for SMTP 550 or 554 errors or SPF check failed messages, then verify your SPF and MX records using the Check Domain Name Resolution tool. Ensure Send to External Domains is enabled, your password meets complexity requirements, and your client uses the full email address with correct ports (995 for POP, 465 for SMTP). **Q: what's the best way to email sending failed** A: Diagnose the exact error source first. DNS misconfigurations require updating SPF and MX records, webmail blocks (AccountFrozen or 503 errors) require CNAME verification and console unblocking, and third-party client failures require enabling POP and IMAP and verifying port 995 and port 465 settings with your full email address as the username. **Q: how do I troubleshoot why an email was not received** A: Verify that your domain MX record is correctly published to route inbound mail, then review your Blacklist, Whitelist, and Anti-spam Level settings to ensure legitimate messages are not filtered. Finally, check mailbox storage limits and IMAP or POP3 sync rules that might be archiving or deleting incoming messages. **Q: what's the best way to email not received** A: The most reliable method is a systematic check of routing, filtering, and storage. Confirm MX record accuracy first, then adjust spam filter thresholds or add trusted senders to your whitelist, and finally ensure your mailbox has sufficient capacity and that sync settings are not removing messages from the server. ## Key terms - S/MIME is a protocol that enables digital signatures and email encryption using PKCS#12 format certificates. - SPF record is a DNS entry that specifies which mail servers are authorized to send email on behalf of your domain. - DKIM is an email authentication method that adds a cryptographic signature to outgoing messages to verify sender identity and message integrity. - DMARC is a policy framework that tells receiving servers how to handle Alibaba Mail is available as agent-callable skills via DaaS.
