System does not accept my password. Can't find outgoing server to send e-mail messages
I have a private e-mail server (mail.fredhadtke.com). I cannot access this mailbox with my password. Same with my i-cloud mailbox. Ive gone through the mailbox settings but I must be setting things incorrectly. What should I do?
MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.5)
