For the particular list of interest, locate the template  MSG_POSTING_REJECT_NOTAUTH  and insert these three lines at the top:

  .TY &DATE &TIME &LISTNAME; auth-drop &FROMID; &MSGREF;
  .* cancel the notification, reduce spam back-scatter
  .QQ

The .TY line causes a log entry so the site admin will have some info about what happened if questions arise later about why a certain message did not go through. The second line is commentary, explaining (mostly for my own benefit) why I did this to my template.  The .QQ instructs LISTSERV to cancel the message it is currently using this template to prepare - and that is the precise answer to your question. Note that in your template the dot on each line must appear in the first column.

Dear site administrators,

is there a way to reject/discard postings received from non-subscribers *without* sending a note to the poster stating that they are not allowed to post?

Thank you very much in advance and kind regards,

Marc Frei
