Within the last two weeks, my mac mail is having trouble sending mail. I'm getting the message "trying to log into thie SMTP account failed." Then I get "Mail can't verify the identity of 'mail.mac.com'." What do I do?
This same email issue just started happing to me this weekend on my old G5 running 10.5.8. I had been using my original .Mac settings up until now without any problem, so I've tried recreating the account using the IMAP settings BDAqua listed in this thread, but now the server keeps rejecting the password. I can however log into my iCloud account thru Safari, so I know the username and password are correct. (Albeit trying to actually click the Mail icon causes the browser to crash, but that's neither here nor there...)
I hope someone can help me solve this issue, but I'm feeling like iCloud has finally turfed the older OSes and you have to upgrade your hardware to Intel processors and your OS to Lion if you want to do something as simple as check your email.
