[Ma-linux] Can someone explain this SMTP error?

[Angelo Bertolli]

The original message that was sent to me contains:

X-Forwarded-To: angelo at freeshell.org
X-Forwarded-For: angelo.bertolli at gmail.com angelo at freeshell.org

But I'm sure the person didn't do that on purpose.  Doing a search for 
those headers online revealed results that seemed to only be related to 
gmail, so I wonder if gmail is adding them.  I thought X- headers were 
mostly ignored anyway.
