Re: Sender Spoofing via SMTP

[Pranav Lal <pranav.lal () gmail com>]

Hi Ansgar,

I was not thinking about disabling the telnet on the client. I was 
under the impression that the user was running a telnet server. As 
other listers have pointed out, this is not the case. Several 
protocols such as SMTP allow telnetting which is very useful during 
diagnostics.

Because that doesn't solve the problem. You could restrict access to 
the
telnet executable for normal users (I'd recommend against deleting 
it,
because it is a useful tool for network troubleshooting), but they 
still
could use a statically linked executable instead. Problems like this 
are
best addressed on the server, not on the clients.
