spamassassin came with evolution (Gnome's Mailer), I never 
configured anything for that.

_I_ cannot find anything suspicious; everything listed there 
seems to be mails I really sent or received.

I tried http://www.checkor.com which Jerry suggested, no problem.
Perhaps this really is a problem with abuse.net .

But anyway: Many thanks to you both.
I wouldn't like to be the one person who sends all the 
"enhancement" mails.
