RTP 6.1 troubles

I’m having trouble setting up mailer(phemail). I have all of the server
information entered into it, but it does not respond. I know networking
works because I can use voyager just fine. Can anyone point out how to
observe what’s happening inside mailer negotiations with server? any debug
settings? sniffer? Also CDROM drive is not recognised. entire /fs
directory failed to be setup during install. I created /fs and fs/cd0, but
no cd found in /dev, so I can’t mount. Ideas anyone?
