Interesting, but that doesn't really give me what I'm looking for. I want to see the full text of the smtp conversation including the text of the email as it is being sent. I can see some of that in the strace, but if it is all there, it would take way too much effort to reconstruct it. What is the easiest way to disable the encryption on the server? -- Bowie ------------------------------------------------------------------------------ Want excitement?
