By not allowing the same user to access two backends concurrently.
One option and the best way is using dovecot director. However, it is soon to be removed from free community dovecot.
Another way is using a proxy (example HaProxy) with sticky IP. The disadvantage of sticky IP is if they are using multiple IP's such as a desktop and mobile connection at the same time.
Thank you! In my configuration already uses a Dovecot director and error messages occurred on the backend mail servers (mentioned in option director_mail_servers).
By the way, I saw that in mail.log of 1st backend error messages more than in mail.log of 2nd backend.
