Does SpamAssassin automatically delete emails that it thinks are spam?
No. We do not intend to censor our customer’s email accounts. The SpamAssassin filter is enabled only to identify possible spam emails. What happens to these flagged emails is up to you. Users often setup message rules with their email clients to delete or forward suspected spam. Even if an email is recieved from a sender on your Black List, that email will be automatically flagged as spam, but will never be automatically deleted.
