We are having the same problem with corrupted messages with the same 
description of missing lines, garbage and other people's email messages 
inserted into the body of the message. Because it seems to happen 3 or more 
in a day, I'm curious if it is triggered by a specific spam message hitting 
the system.

Our mail relay is running Solaris 9, sendmail, milter, and spamassasin 2.43.

I have an example of a section from one message that was corrupted today, 
and it is very similar to the one you described. The X-Spam-Status and 
X-Spam-Level headers were missing from the header (not normal for our setup).

I'll post any solutions we come up with, and thanks to everyone for their 
ideas!
