Luckily it does not happen that often any-more, but this week several of the mails of this list got into spam. (I use SpamAssassin.)
They all got marked with this:
 3.3 RCVD_IN_SBL_CSS        RBL: Received via a relay in Spamhaus SBL-CSS
                            [2600:3c00:0:0:f03c:91ff:fe96:b959 listed in]
                            [zen.spamhaus.org]

Is this useful information, or should I not bother the list with this?

It happens via gmail, too, but only on a small fraction of posts.
