Please tell me how I can stop the huge quantities of SPAM that comes to

&LISTNAME-request@&MYHOST (i. e. [log in to unmask] in the case of my list).
Is there a way I can configure the list header so that messages sent to
&LISTNAME-request@&MYHOST by non-subscribers are rejected and sent a
form letter based on a template that, preferably, I can alter?

Postings direct to Alpine-L from non-subscribers are currently rejected, but not messages
sent to &LISTNAME-request@&MYHOST
Thus, I get a terrific amount of spam at Alpine-L-request.

Thanks.

Harry Dewey, listowner, Alpine-L
