Does anyone know how DH's installation of SpamAssassin, as accessible through SquirrelMail, is configured? Is it a fully default installation, with default rules, untrained with no Bayesian classification of incoming mail? Customized and souped-up? Is there some DH guy training SA behind the scenes on large quantities of verified spam?
Do you use SquirrelMail's filter? Or do you completely bypass it, procmail all your mail to your local setup of SA?
