I have my Gmail account set up for IMAP, and use it in Mail. However, as of this morning, Mail can't connect to either the IMAP server or the SMTP server. Whenever I try to connect to the IMAP server, it gives me the following error: "The server 'imap.gmail.com' refused to allow a connection on port 993." I've checked repeatedly and all of my settings are as the Gmail website says they should be. Does anybody have any idea how to fix this?
