Resolved El Capitan - Mail disables active account

[awfulmacer]

My Mac make preloaded with Yoshemite. After I was prompt from App Store I decided to upgrade to El Capitan.

Ever since Mail refuses to work properly. In that, every time I restart the laptop or the application my email account is deactivated and I need to go to Preferences->Accounts and re-tick "Enable Account".

Anyone else has a similar problem? And do you know any solution?

There were some big changes to Apple Mail in El Capitan. See these two articles on troubleshooting Maill.

The solution seems to be in the settings of the mail account. Your "Alias" and "Description" HAS to be your email.
Mail->Preferences->Accounts.

Also update 10.11.5 might have helped.
