Exactly which application should be processing the whitelist and blacklist spamfilter policies? I'm using Rspamd. If I use 'rspamc' to test a mail item, will it use the w/b data? I'm not sure exactly where in the postfix / dovecot pipeline that this data is used. Also, assume mail comes from [email protected]. Is it enough to use "example.com" in the sender spec? Is the @ required? That would require entries for each subdomain. Is this text processsed as a regex? There's no info about this stuff in the ISPConfig doc - only details about the form entries. Thanks!
