There is a problem in Evolution 3.8.5 due to changes icloud made to their servers. It disallows imap connections due to authentication issues.
The following link to gnome.org indicates that a patch is available for Evolution 3.10 (the problem does not occur in 3.12).

Milan suggests "Ask your distribution to use the patch from the [1] and provide an update for you."
Is there any chance of this for Centos 7, as Evolution is currently rendered inoperable with iCloud imap.
