With the following error message (2nd frame), the explanation order of the types contains in "Mailing_Queue_Entry" is reversed. The real statement of Mailing_Queue_Entry is

public type Mailing_Queue_Entry:
  empty,
  relay(Mailing_Queue_ID    mailing_q_id,
        Mailing_Recipient_ID  mailing_recipient_id,
        String              user_from,
        String              file_name,
        String              header,
        String              recipient,
        Send_Timeout        timeout,
        Send_Tries          tries).

and we can see, it begin with "Mailing_Queue_ID" not "Send_Tries" as written in error message.
