If password begins with '{' then Dovecot treats it as
"{scheme}password". Otherwise { and } inside the password shouldn't
matter. It's possible to have '{' as the first character in password if
you make your passdb return the {scheme} prefix always. I guess you're
storing passwords as plaintext, because otherwise this shouldn't be a
problem at all. So make sure all passwords have a {plain} prefix.
