Hey, Mark, thanks for your input.

Yet I fail quite to understand what is letting it through.  I went over
my sender filters, and only one address not on the subscriber list is
allowed to post.  I've taken this away now, but the mail still gets
through.

AFAIK there are now no addresses beyond the subscription list that
should be allowed to post.  Apart from that, there are just some
addresses that are explicitly allowed as incoming addresses.  Have I
overlooked something?  

I'll enclose the mail that gets sent through.
