Issue Description

After the customer feedback has made the SSL content identification, the attachment of the QQ mailbox cannot be downloaded.

Handling Process

1. After adding the IP of the test PC in [System] – [Gengral] – [Global Exclusion] – [Custom  Excluded Address] , it will be downloaded normally;
2. Disable the SSL content recognition policy, which is also downloaded normally.
3.When the browser opens the QQ mailbox and downloads it, it finds that the following link is not successful:
localhost.ptlogin2.qq.com
stockweb.mail.qq.com
rl.mail.qq.com
4.Global exclusion as above address test is normal, adding these addresses to global exclusion does not affect auditing and business.

Root Cause

The qq mail attachment corresponds to the server link being caused by the device proxy and the attachment cannot be downloaded.

Solution

Add the four domain names localhost.ptlogin2.qq.com, stockweb.mail.qq.com, and rl.mail.qq.com to Global Exclusion.
