user password in mail-filter plugin

[Thomas Möhle]

So let me show you my config, just to be sure:

/etc/dovecot/conf.d/auth-sql.conf.ext:
passdb {
  driver = sql
  override_fields = userdb_pass=%w
  args = /etc/dovecot/dovecot-sql.conf.ext
}
userdb {
  driver = prefetch
  result_success = continue
}
userdb {
  driver = sql
  args = /etc/dovecot/dovecot-sql.conf.ext
}
