Email Account Password
I have the same problem with Mail after last update.
No connection to my Mail Server. The password for the accounts is not in the Keychain.
I have setup new passwords for all accounts by my ISP.
After i entered the new password in mail all should work now.
Why is the passwords for my email accounts not shown in the keychain?
Mac Pro, OS X Yosemite (10.10.4), null
