I don't think it was set successfully. Generally, there is no problem if the setting is successful. In addition, the port of Apple mobile phone is 587 by default. Let's see if the port is set correctly.

The steps are as follows:

1. Open the settings on your phone and select E-mail, mailing list and calendar-add an account.

2. Many practical mailboxes will appear on the mobile phone by default. Because the mailbox I want to add is qq mailbox, so I choose "MOIL QQ mailbox" as shown in the figure. Note: This depends on the type of mailbox. You can choose any email address.

3. Fill in the email name you want to set in your mobile phone, such as "QQ", and then fill in the account number and password of QQ email. The final "description" does not need to be changed and filled in, as shown in the figure: After filling in the account number and password and other related information, click "Next", which means that your mobile phone will automatically verify your email address, and your email address will be added after verification.
