Once again for no good reason, at about 1830 local on Dec 15 (that would be 2330 GMT), Aquamail failed to connect to apple's incoming mail server. (we had this issue in 2013 when apple changed a protocol requiring just the login name, and not login@mac.com). The problem persisted and yesterday I deleted the Mac mail account on Aquamail and re-added it with a new app-specific password. No luck. Aquamail was updated overnight, so I tried again this morning, same issue. Incoming Mail server (IMAP): Error connecting. Failed to connect to mail.mac.com. I tried using just username and also username@mac.com as the login, and I tried with SSL and STARTTLS. No luck. Ideas? Other users having this issue? The only change from my end was the addition of an Apple TV to my home network. Coincidence?
