People,

My mail server guru sent me the response below when I asked him about 
getting error messages when I post to the RCM list - can someone tell me 
if his analysis is correct?:

Thanks,

Phil.

Your mail got altered at the mail server that received kolabsys.com [1]?

Authentication-Results: ext-mx-in002.kolabsys.com [2] (amavisd-new);
   dkim=pass (1024-bit key) header.d=pricom.com.au [3]

1. When it was received by ext-mx-in002.kolabsys.com [4] from pricom
server 14.202.193.218, your signature was fine and it had passed

2. Something happened on one of these servers (10.5.9.1 or 10.5.3.2)
which altered the message body, after which your signature no longer
verifies.

3. There is no issue with your DKIM-Signature as it verifies on
ext-mx-in002.kolabsys.com [4]

I have cut-pasted the headers from the original mail below
