qmail at top-consulting

I am having a world of trouble with messages that contain a References
header whenever that References line goes above 1000 characters.
As per the RFC any one line can't have more than 1000 characters which
is totally fine. The problem however is that messages from a certain
person are coming up broken. Looking at the source of the messages I
see that the References line has been broken at the 1000 character
mark and an empty new line has been inserted. All e-mail clients
interpret that as being the end of the headers.
I have recorded the SMTP conversation as I receive this particular
message and here's what happens at the 1000 character mark:
@400000004d66d1113841ec94 11008 < 97B-8278-3415983066^M
@400000004d66d1113841f464 11008 < ^M
@400000004d66d1113841fc34 11008 < 13@
Is that cutoff done by qmail itself or am I receiving that from the
remote end ?
When the same person e-mails my Hotmail account for example, the
message arrives broken at the same spot but there's no new line
inserted like with Qmail.
What's going on ?
