1. You need "matches" rather than "contains" for a regular expression
match.

2. The newlines in $message_body are replaced by spaces (supposedly to
make it easy to search for phrases, but that was probably a bad idea).
So you probably want "\\N\\bHANDLE: .*?123\\b" for your pattern:

  (a) Doubled \\ because it's inside "".
  (b) \N suppresses string expansion which would interpret the following 
      \ characters
  (c) .*? rather than .* for much improved efficiency - it will step
      along one char at a time looking for 123 instead of going to the
      end of the message body and stepping back one char at a time. In
      fact, you would do better with \D* instead of .*


Try

  if $message_body matches "\\N\\bHANDLE: [^\\dA-Z]*(123|ABC)\\b" then
    save file_$1
    finish
  endif


Untested. Probably won't work exactly like that, but something similar 
will.
