What is Vanke's mailbox installed on Apple's mobile phone?

Take QQ mailbox as an example:

The most common method is to associate QQ mailbox in the settings of mobile phone, as follows:

First, click Settings-Account → POP3/IMAP/SMTP/Exchange/carddav/Caldav in the QQ mailbox of the webpage, and check IMAP/SMTP service (this is, you can log in to the mailbox with a third-party application.

Open the settings options on the iphone desktop.

→ Select email, address book and calendar in the account column, and select Add New Account. Select the "QQ mailbox" icon and enter the basic information of the mailbox. When you enter the format of the mailbox in this column, you can fill in the name and description at will. When filling in the email address, xxx@qq.com format is usually filled in, but some vip email addresses may not be set.

→ Set the email reminder mode, and the email will be added successfully after setting.

Of course, the second method is to download the APP software of QQ mailbox directly. The use of this software is similar to that of mobile QQ. Basically, you only need QQ number and QQ password to log in. The operation is simple, but you must install another software. When the software runs in the background, it may bring extra power consumption to the mobile phone. Its advantages are convenient and simple use, powerful functions without checking IMAP/SMTP. E-mail can't be sent out, and the probability of not receiving it is very low.

Thank you for your adoption.
