Apple Mail account suddenly offline, smtp offline

iMac 27" (late 2009) updated to Mac OS X Yosemite 10.10 and Apple Mail 8.0 (1990.1) 17th October 2014.

Mail accounts in Apple Mail where working as years before until Yesterday, 3th November 2014. Suddenly 2 out of 3 accounts where offline showing the warning triangle icon on the right. Command "go online" and "syncronize" has no effect. Activity in Mail is showing no try to connect. Looking into the account config I see that the SMTP are "offline".

I checked everything and compared to the settings of the one account which is still normal working. Everything is identically set up. Only differences are the domain names, username and pwd. The domain names are on the same external virtual hosts and have same configs. The on the iMac faulty accounts are working on iPad and iPhone like ever and from the same internal network. My hardware firewall or the external mailserver can not be the reason.

I deleted 1) SMTP config, 2) whole mail account, 3) all corresponding keys in keychain and was setting up from new. No chance, they show SMTP offline and do not go online in IMAP. Next was trying to give account #1 the SMTP from the working #3. The SMTP #3 shows fine but near the inbox of account #1 i have again the warning triangle. No go online, no sync, no action in the activity window.

I go setting up Mail with these accounts in a new user. Mail was totally empty as I started config of two accounts. After doing all they where at the same point. No connection possible.

Why is this happend suddenly and after more than 2 weeks after Yosmite update? Why is one account working, two others not anymore?

iMac (27-inch Late 2009), OS X Yosemite (10.10)

What the **** are my mail accounts configured in Mail preferences > Accounts AND ALSO in System Preferences > Internet Accounts???

iCloud or anything weird cross-linked things for this I hate you!

If I mark one of my invalid mail accounts within the later it calls to enter my password. Doing so it says "Unable to verify account name or password". See img's below:

Again #1 and #2 accounts are invalid, #3 account is valid and a different domain name but on the exactly same virtual hosting. The rest are internal accounts pointing to my Mac OS X Server and are doing well.

Before I delete these accounts in System Preferences / Internet Accounts with maybe loosing some Data, is there any idea about fixing this?

Thanks!

OK, I deleted in System Preferences > Internet Accounts my invalid #2 account and set it up again.

Same error "Unable to verify account name or password.

Again.

Without any change (just surfing via Safari) the invalid accounts come up suddenly and are working fine.

Now I do nothing, no restarting Mail, no rebooting iMac. No actions in System Preferences > Internet Accounts. Nothing.

Let's wait and see.

After doing some cleanup in my inbox and sending some messages I went away from the iMac for maybe half an hour.

The Mac was correctly screen protecting after few minutes. Coming back by enter my login Mail shows again #1 and #2 account invalid while #3 is fine.

Restarting Mail has no effect. Going to System Preferences > Internet Accounts and selecting e. g. #1 account the password window appears like described before including the error message in the second step.

Strange but no fun at all.

Finally the problem solved: Internet Accounts preferences can't connect to the account …

My own fault.
