I have been investigating this issue as i have also come across it,
Well as the postfix queue format is not
documented my assumptions were just guess work so correct me if i am
wrong, i was under the assumption
that the integer values at the beginning of the queue file represent
the side of the message.

What i picked up was that even after the milter inserted the extra
headers to the message these values
remained the same the perl module resonsible for reading the queue
file and processing it was then
unable to due to the fact that it was not reading to the wrong place
within the queue file.

P.S and yes postfix on Centos 5.1 comes with milter support built in.
