Does anyone know what kind of service that is? And is there a way to find out which process is listening on a given port (so that I can kill it)? 587 is for SMTP "submissions" meaning new messages (from users) being injected into a server, versus relayed mail from other 'net mail servers, which would use port 25. There's an RFC for it, but I don't know of any MUAs that implement it. Eric -- Eric Sproul, Systems Administrator Cornerstone Networks Inc.
