you defined a custom iterate_query but the debug message says it uses the built-in default:

> using built-in default iterate_query: SELECT username, domain FROM users


Please check if your config is included:

conf.d/10-auth.conf: !include auth-sql.conf.ext

conf.d/auth-sql.conf.ext:

userdb {
  driver = sql
  args = /etc/dovecot/dovecot-sql.conf.ext
}

Maybe your dovecot-sql.conf.ext is somewhere dovecot does not look for it.

Besides you have configured mysql userdb twice:

> userdb {
>  args = /etc/dovecot/dovecot-sql-master.conf.ext
>  driver = sql
> }
> userdb {
>  args = /etc/dovecot/dovecot-sql.conf.ext
>  driver = sql
> }



Best regards,
Gerald
