reading the mail log ...

We have taken and sanitized a log extract, which was a live example tracking down a specific user's ('paulhill') asserted inability to send email. We sanitized the userid, source IP and host name and recipient userids, to appear to be from our example server outsmtp.example.com ; the range 172.16 ... 31.x.x is reserved in RFC 1918 as one of the dedicated private IP space ranges. That RFC states that such IP ranges are recommended to be dropped at any border router which does not 'know' it is in local use.
