Hello I am using amavis as a spam filter. Every few days and email
slips out and passes all my security checks. I am not sure what is
causing the problem. I disabled dns lookups in the transport today but
I doubt that this will do the trick. I copied this lines from my
master.cf. Is there something else I could add to make sure emails
dont slip through? Thanks.
