Thanks Michael. The "reason" is stated a little bit differently from my side 
but it boils down to the same thing. Here are the full headers as requested by 
Reco:

Indeed! I hope it's not a mistake of mine (usually I proofread my emails before 
sending them but who knows...).

Why would they do that? ">" is rather usually indicated to insert quotations 
isn't it?

Thanks for the feedback.
If it's Debian ML responsibility, better to know it because my email provider 
won't be able to do anything about fixing the issue.
