What to do with SSL connection errors in Foxmail

How can this mistake be solved? In fact, the solution is very simple.

1, in the Foxmail right mail account list to select the wrong mailbox, mouse mail Click, select "Properties." Or in the menu bar "Tools" select "Account Management", and then select the appropriate mailbox account.

2, click the "Advanced" button, in the Advanced settings to remove POP3 "This server requires secure connection (SSL)" In front of the check.

3, click OK button, and then collect mail again, is it normal?

PS: It is not clear the cause of this problem, because I used to be the default settings, are normal. And the same 163 mailbox, other accounts check the SSL is not a problem, so the biggest reason may be the mailbox service side what the adjustment caused by the Foxmail client error. Only one temporary solution is available here.
