If you check your previous message at 
<http://mail.python.org/pipermail/mailman-users/2007-April/056811.html>, 
you will note that these are not being inserted as actual headers in 
the message, although it probably appears that way to you.  There was 
a blank line between the last "real" header and these lines, which 
made them part of the message body.

If you look at the original message as you sent it, it had the MIME headers:

Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: 7bit

So, SquirrelMail was sending things just fine, without a 
content-transfer-encoding of base64.  And it doesn't look like 
MailScanner changed anything here.  Of course, the original message 
was probably 7-bit clean in US-ASCII (as opposed to using eight-bit 
accented Greek characters), so without more information we don't know 
for sure where the conversion to base64 was happening.

The clients should still have been able to deal with base64 in a 
transparent manner, so this is clearly also a client problem.
