Replying to the PROCMAIL mailing list

I picked up the following recipe from a fellow NetCom users' PROCMAILRC 
file:

        :0 fhw
        * ^Return-Path:.*procmail-request
        | $FORMAIL -i "Reply-To: 
procmail(_at_)Informatik(_dot_)rwth-aachen(_dot_)de"

Which works fine except for when I send receive email from the list 
managing email address 
"procmail-request(_at_)Informatik(_dot_)rwth-aachen(_dot_)de".  
When I receive email from that address, I don't want to reply to the 
LIST, I want to reply to list managing email address.  So I've modified 
the recipe as follows -- it's a very simple change, but one that will 
hopefully spare the list from some further grief.  It's important that 
the colon is in the third line as what we are wanting to match is the 
'From:' line and not the 'From' line:

        :0 fhw
        * ^Return-Path:.*procmail-request
        * !^From:.*procmail-request
        | $FORMAIL -i "Reply-To: 
procmail(_at_)Informatik(_dot_)rwth-aachen(_dot_)de"

Anyone see any problems with this?

Lates!
