We have run Listserv (Windows) behind a spam filter for many years. We receive notifications of all spam to the lists which has not be bad. We have approximately 50 lists with max several hundred subscribers and only one or two get much
spam. Our lists are closed with subscriber approval which may help too.
If nothing else, have the spam filters check SPF to prevent spoofing and skip any rules based detection.

Hello,
We use Listserv 17.0 in RedHat. We had three incidents of 'phantom approval' this year and I had to ask the not aware editors to change the webmail settings.
I tried to use procmailrc to block the keywords. It worked on the regular account on the same server but not the listserv account. I thought that it might be aliases
take precedence of procmailrc. We do not want to use a spam filter because it would cause some false-positive. Any insight suggestion to block some keywords (e.g., bitcoin, BTC wallet, and BTC address) from incoming post request?
Thank you,
Shinn
