OK, here we go again. There was much written about this in the forum back in 2013 and a few tidbits since though I just spent the past few days trying to troubleshoot an authentication issue with my mac.com IMAP account, which occurred shortly after latest update. I can get my email through the iCloud web portal and from my MAcBook Pro with Mac Mail, though can no longer authenticate from Aqua Mail.
Settings are well published:
User id is full email.
993 and imap.mail.me.com incoming
587 and smtp.mail.me.com outgoing
Been trying all security types.
Any insights?
Otherwise, still love this app! Truly well done.
