this is the whole acl rule

acl_check_mime:
accept hosts          = :
# --- accept messages for abuse / postmaster
accept condition      = $acl_m_pm
deny   decode         = default
       condition      = ${if >{$mime_anomaly_level}{1}}
       message        = This message contains a MIME error ($mime_anomaly_text)
# --- Check MIME boundary delimiter according RFC2046
deny   condition      = ${if match{$mime_boundary}{\N( |\t)$\N}}
       message        = MIME boundary delimiter ends with whitespace
deny   condition      = ${if >{${strlen:$mime_boundary}}{70}}
       message        = Too long MIME boundary delimiter
deny   condition      = ${if match{${lc:$mime_filename}}{\N(\.com|\.vbs|\.bat|\.pif|\.scr|\.exe|\.js|\.mpeg|\.wmv|\.wav|\.wmp|\.asf|\.zip|\.rar|\.mpg|\.bmp)$\N}}
       message        = Nie obslugujemy tych zalacznikow
accept authenticated  = *
warn   !hosts         = +relay_from_hosts
       condition      = ${if >{$mime_anomaly_level}{0}}
       set acl_c0     = ${eval:$acl_c0+20}
       set acl_c1     = DEMIME(20) found MIME error ($mime_anomaly_text); $acl_c1
accept
