Package: spamass-milter
Version: 0.3.2-1
Severity: important

Dear Don,

when a message is detected as spam, it is prepended with a waring message.
The original message appears as a mime attachment.

This attachment has a bad Received: header like this:

Received: from vwp12xxx.webpack.hosteurope.de (vwp12xxx.webpack.hosteurope.de 
[5.35.232.xxx])
        by eroski.aldebaran.de(8.14.4/8.14.4/Debian-4) with ESMTP id 
t06Df1fZ019601
        Wed, 10 Dec 2014 14:38:06 +0100
        (envelope-from <scr...@wp11273xxx.server-he.de>

Note the following problems:

1. The semicolon at the end of the id is missing (RFC 2822
requires it like "id t06Df1fZ019601;").

2. The "(envelope-from"... comment does not have a closing parenthesis.

3. Most importantly, the date is wrong. This email was received on 06 Jan 2015. 
It is very strange that we have a wrong date here because the clock of the mail 
server running spamass-milter and sendmail has probably been correct; it is 
adjusted using ntp with several servers in the net. Also, all the other 
date headers in the mail are correct and if the clock would have been 
wrong, more header lines should be wrong, too. 

Point 3 leads to false positive.

Here is a quote of most of the
message, with only the end (with content) cut off, and some sensitive
info replaced with "x".
