Hi,  

Some of my users are receiving some of the mail not "decoded". The message
is received with all the smtp commands that are used in DATA section, like


Return-Path:  
X-Original-To: XXX at XXXX 
Delivered-To: XXX at XXXX 

….. 

This is occasional and if the message is resend again by the source, is
received ok. 

Can this be a mailscanner issue? 

I think it is unlikely. I have seen this behaviour before with an
application that is not using CRLF correctly for line endings. In order to
find out the cause I would start with dumping the SMTP connections and see
if the SMTP messages are using CRLF in the right way. I guess WireShark is
your friend here.
