Queue file corruption with MS + postfix +debian

i have this problem with some debian boxes showing a few corrupted queue
files.

the full scoop is this:

most of them were running dibian stable (woody) with postfix 1.1 and
amavis. then we decided to move them to postfix 2.1 + mailscanner to use
some of mailscanner's capabilities such as rules.

so instead of doing a full dist-upgrade to debian testing we took
diferent paths for each of them to see what would happen.

so we have some boxes with:

- postfix from backports.org and mailscanner 4.30 and perl 5.6.1 from
woody (lets call them "type 1")
- postfix from debian testing, mailscanner 4.36 and perl 5.8.1 partially
upgraded used apt-get's "pinning". most packages are still from woody,
with a bunch of depencies from "sarge" to run MS + postfix 2.1 (lets
call this kind "type 2" boxes)
- an ancient redhat 7.2 with postfix 2.1.4 + mailscanner 4.35 with perl
5.6.1 (call them "type 3")

In "type 3" and "type 1" machines i only have corrupt queue files
ocasionally, 2 or 3 a month maybe, but in "type 2" boxes (the ones
"pinned" with sarge packages) i consistently have 3 or 4 corrupt files
every day. postfix always claims the same: "rcpt count mismatch"

I assume this is something specific to my "pinned" debian, since it
doesn't happend at all with red hat and very litle with boxes using
backports.org's postfix. Bellow there's a list of packages from the
"pinned" machines and some logs.

strange as it is, if i return the corrrupt messages to postfix's "hold"
queue, so MS scans them again, they end up delivered normally.

i even mailed Julian this week but he couldn't reproduce the error, so
does anyone have any idea of what's wrong ?

BTW. i have a workaround to this problem (a script to return corrupt
messages to the hold queue) but what i really want is to _understand_
what's going on.

TKS,
