    Hi Jacob,

    Latest putty (0.58). The event log looks like this:

    2005-11-01 00:36:27 Local port 25 forwarding to yoda:25

    I initiated all those connections with telnet localhost <port>. There
    was a telnet to 80 in between the 25 and 443 but you can see nothing
    happened.

    This is netstat:

    freshwater Administrator$ netstat

    freshwater being the localhost. So there's a local connection to 25,
    must have been sending a mail, and some connections to remote 80 (like
    this session) but nothing to local 80.

    It does work sometimes, so I think it is something grabbing that port,
    but I don't know what.

    Still baffled.
