I’d like to start using the server level junk mail filtering on dreamhost but I wanted to know if it was possible to cause all messages caught by the filter to receive an auto response notifying them that I didn’t get their message.
Not with the DreamHost junk filter. Maybe if you installed SpamAssasin yourself or the like. Not that this would be a good idea - if the junk filter is catching spam with bogus or stolen email addresses then why bother wasting resources spamming those back?
