What should be done when the post office encounters inability to send or failure to receive some emails?

After the mail service is activated, what should you do if you encounter such problems as being unable to receive mail, being unable to send mail, failing to send to foreign email addresses, or the sent message being placed in the spam folder by the recipient's system?

Answer: Please first go to Management Center > Mail Management and click “Mail Diagnosis”.

Try the solutions prompted by the system. If the problem still persists after handling, please submit to Q&A and contact customer service to manually investigate the cause. Thank you!
