I don't know when it started, Foxmail couldn't charge 163 of the mail. Anyway, the computer version of the 163 mailbox is not used, there is no way to solve the problem. Later found that the total use of mobile phone to see 163 of the contents of the mailbox is sometimes not convenient. So I found a solution.
Here is Foxmail's error:
So I set up a 163 of the port in the mailbox, as follows:
You want to come here and have no problem. But not yet.
Then I looked carefully. Foxmail hint, originally is to modify the settings in the Foxmail. The following is set in Foxmail, the account---the server, the SSL two ports on the √ can be.
So Foxmail can continue to charge 163 of the mail. If you want to receive an email that you have not received before, click on Foxmail to receive all accounts, so that before 163 of the Mail can be seen in the Foxmail.
