okay, so i've fiddled around a bit and reckon i've got this working pretty
well now. i wanted to stay with release 1.4.1 so i can keep using the
freebsd package as it's easier to maintain but i needed MO concatenation.
after looking at some inbound UDH i put this script together. i've added
comments so everyone can see how it works:

hope it helps someone!
