[exim] demime/decode carry out

I am a newbie with exim & exiscan. (Just about half a year)
I've exim-4.33 on Debian 2.4.18

I will to enforce demime/decode with exiscan, but have no results.

Quotation from my configuration file:

  begin acl
  .........
  warn  message = This message contains a MIME error ($demime_reason)
          demime = *
      decode = /tmp/$message_id
      condition =  ${run {/bin/cp /home/spool/scan/$message_id/$message_id.eml /tmp/$message_id}{1}{0}}
      #condition = ${if >{$demime_errorlevel}{2}{1}{0}}
  warn    message       = Relaying denied

  warn message = HTML mail is not accepted here
          condition = ${if eq{$mime_content_type}{text/html}{1}{0}}

The hint it necessary to me is I am trying to write mime headers from
    mime.c to postgresql. I haven't even seen either unencoded
    files in my /tmp, or any indication co-operation with pgsql.

I know it schoud be visible only in case
- if the message has a MIME-Version header.

Please, drive me onto right way, because I cann't seize where I am fool.
