Problem with Airmail 2 and iCloud
I have been using Airmail 2 for some time with an Exchange account, AOL account for junk mail and an iCloud account. My iCloud account suddenly won't work despite my following directions from Apple re: IMap and SMPT. This seems simple enough but can't fix.
iMac (27-inch Mid 2011), OS X El Capitan (10.11.4)
