Odd, I'd've expected an error at the "or" because of that's where the
first missing open-brace is.

Well, let's see. The syntax for "and" is:

    and {{<cond1>}{<cond2>}...}


and similarly for "or". The keyword is followed by a curly-brace
enclosed set of conditions, each of which is also enclosed in curly-
braces. You're missing a bunch of braces. Extra whitespace can help
visualize where they go. Is this clearer? (Use a fixed pitch font
to see what I'm seeing)

    condition = ${if and { \
        {or { \
        {eq {$local_part} {addr1}} \
                                 {eq {$local_part} {addr2}} \
        } \
                           } \
                           {eq {$interface_address}{127.0.0.1}} \
                         } \
                  {1} {0} }


BTW, what's PERL got to do with it?
