No, I'm using Bogofilter and it works perfectly. I'm not talking hypothetically. AFAIK, it does some Bayesian statistical analysis.
Bayesian filters are basically just a cheaper / worse version of what an LLM filter would do. Very easy to beat. Especially if the spammer is using an LLM to write a semi-unique email for each recipient.
As I've said, I'm not interested in theoretical arguments. All of my domains wildcard forward to the same email address, too. Filtering client-side has never been a problem.
