After a few days of using El Capitan I decided to do a clean install today.
As always I backed up ~/Library/Mail
and put it back after the clean install.
When I opened Mail after that, there were no accounts, no local mailboxes, no mail!
Since the I tried to restore every file that could be associated with Mail I could find from a TimeMachine backup:
~/Library/Mail
~/Library/Containers/com.apple.mail
~/Library/Preferences/com.apple.mail-shared.plist
Nothing has changed from that.
My Mails and Mailboxes are located in:
~/Library/Mail/V3
My Accounts are stored in the only file left in V2:
~/Library/Mail/V2/MailData/Accounts.plist
But Mail seems to ignore the whole ~/Library/Mail
folder. Any ideas what I could do?

I decided to restore my mails by hand. That took me a few hours, but now I am back to normal.
Here is what I did:
What I realized after going through all those steps, is that the accounts inside of
~/Library/Mail/V3
are not named by there account names anymore. Instead the consist of a cryptic combination of numbers and characters. Maybe that was the cause why Mail did not import anything.My guess is, that accounts are now referenced by a number/character-code out of security reasons. However, that leaves me wondering how to do a proper backup of mail for a clean install.
