X-Amavis-Alert: BAD HEADER Improper use of control character (char 0D hex)

[br...@sptroth.com]

Hello all

Environement:
I'm using Amavisd-new 2.2.1-5 (for Virusscaning) with Postfix 2.1.5 as MTA
and Spamassasin 3.0.3 on a Suse linux 9.0 Host

Normal message process:
SMTP  >  Postfix  >  Amavisd-new  >  Postfix  >  Spamd > Relay Host

Failure:
When a special message is incoming (like below) amavisd-new
"corrects" the bad header and adds an additional header, but other headers
ar lost.
So the message cannot be procesed as spam (subject line is empty)
and will be delivered as a clean message.
SpamAssasin works fine.

Question:
Has someone any idea how to fix this problem

Regards
Bruno
