Hi all!
I have e-mail user1@my_domain.com  and  user2@my_domain.com.
From user1@my_domain.com  all mail's was forwarded to user2@my_domain.com. All worked fine.
User user2@my_domain.com was created a little incorrectly for me (whith MAILDIR_HASHED = True and MAILDIR_APPEND_TIMESTAMP = True  after last update), so it was deleted and recreated (whith MAILDIR_HASHED = False and MAILDIR_APPEND_TIMESTAMP = False).
And now, when I want add forwarding to user1@my_domain.com, I get next error :
Error: IntegrityError(1062, "Duplicate entry 'user1@my_domain.com-user2@my_domain.com' for key 'address'")
How can I delete this key?
And why this key was not deleted when user2@my_domain.com was deleted?
Thank you.
