What should I do if I can't send an email from QQ mailbox?

The reasons why the email client can't send an email and the solutions:

1. First, send an email to yourself. If the email is normal and you can receive it, it means that everything is normal and there is no problem;

2. Check the mail filtering settings. Click "Settings" in the upper right corner of the email page to open the settings page, and click "Filter" to check whether the filtering conditions are set improperly;

3. Check the anti-spam settings. Open "Settings" in the upper right corner of the email page, open the settings page, click "Anti-spam", and then click "Set Blacklist". If a normal email address is found in the blacklist by mistake, you can receive a letter from the other party after deleting it from the blacklist;

4. Check whether there is the other party's mail in the spam box. If there is, it means that it has been misjudged by the anti-spam system. Select the mail, and then click "This is not spam", and the sender will be added to the white list to ensure that he can receive his mail in the future.

5. Add the email address of the other party to the white list. The setting method is as follows: click the "Settings" tab, then click the "Anti-spam" title, and click "Set White List" in the "Anti-spam" content page. Enter the email address to be whitelisted in the edit box on the left of the "Email Address Settings" page, and click "Add to Whitelist" to display the address in the list box, and the setting is successful;

6. If all the above tests are normal, the mail may not be sent to the server of QQ mailbox due to line and mail server failure, so you can contact the sender.

7. Your mailbox has sent too many emails, which has been banned by the system. I suggest you contact Tencent customer service to reopen your email!

summary: the above is the reason why qq email client can't send email and the solution.
