[exim] Opposite to $sender_address.

Hi all

In my exim log file I have the follwing entries


2006-02-20 15:52:56 1FBBT6-0003M3-0s H=ctb-mesg7.saix.net [196.25.240.77] F=<debbie@???>
rejected during MIME ACL checks: REJECTED ATTACHMENT (bmp)

What I was hoping to achieve is that the messge as well as the rcpt to address will appear.
e.g. REJECTED ATTACHMENT (bmp) (rcpt is: bclark@???)

My acl is like so.

acl_check_mime:
# File extension filtering.
deny   set acl_m1 = ${extract{-1}{.}{${lc:$mime_filename}}}
message  = This message contains a prohibited file extension ($acl_m1)\n\
log_message     = REJECTED ATTACHMENT ($acl_m1)
condition       = ${if match{$acl_m1}{\N^(avi|asf|ade|adp|asx|asp|arj|\
                                         bat|bin|btm|bas|bmp|\

                                         rar|\
                                         url|\
                                         vb|vbs|vbe|vxd|vss|vst|vob|\

                                         )$\N}{1}{0}}

I need the variable that is the opposite to $sender_address.

If anyone could assist me, I would be most grateful.

Kind Regards
