smtp is asynchronous. if your filter breaks, postfix will keep mail in the queue until you fix the filter. This should be enough if you monitor your filter (which you're supposed to do if you care!). if this isn't enough, run multiple filters and use a load balancer. > Is bypassing of filters (mail filter and content filter) possible? > would you bypass your firewall? your anti-virus? your IDS? ... No? so why bypass the smtp filter?
