iCloud not working on iMac but other devices
Hi there
My .mac emails have worked for years on my iMac with no issues. It was set up originally automatically by the mac - no user input into smtp or map details. I now get "Connections to host p41-imap.mail.me.com on the default ports failed." error and the account is offline. I can access it via the web and my other devices just not the iMac.
If I go into Mail preferences, choose the iCloud account and server settings - Outgoing mail account is set to None. I can change it to the iCloud account in the dropdown but it lasts a few seconds before reverting back to None.
If I edit SMTP server list and create an entry for the iCloud and try to get the account to use the new server it just reverts to None again.
I've disabled mail in System Preferences - iCloud but that didn't work. At a bit of a loss now and I'm not sure what the consequences are if I delete the account from my machine and reinstall it.
Any help gratefully received.
Many thanks
Jon
