Re: [exim] Rule invalid recipients

Here the complete config:

          logwrite = RATE USER EXCEEDED: $authenticated_id -> $sender_rate/$sender_rate_period (max $sender_rate_limit)

  accept  authenticated = *
          set acl_m_user = $authenticated_id
          condition = ${if exists{$spool_directory/blocked_authenticated_users}}

I found the rule interesting but I do not understand if it applies to invalid containers or incorrect logins via smtp.

I would need a little help to understand the purpose of the rule, if someone is so kind to help me.
