Block recurring List Server attempts

Postby dunc » Wed Sep 13, 2017 4:25 pm

I use either the "password" or "must be a subscriber" methods of controlling access to all mailing lists. Although both work, the server is getting hammered by multiple bad requests. Is there a way to add these offending IP addresses to the blocked sender IP list, similar to the blocking for SMTP server logins? Would need to have multiple bad requests before blocking.

Something we may look at improving in future versions. But currently the only way would be to analyse the SMTP log files for the connecting IP address and adding manually to the SMTP access control deny list.
