Do you have ipchains / iptables rules on your machine which
drop unwanted traffic..
To setup a new TCP connection the client ( your telnet program
in this case ) sends a packet marked as a SYNCHRONISE ( SYN )
and the server is expected to respond with an ( ACK )
If the local server isn't accepting connections ( because it
doesn't exist, or it is refusing connections ) then you won't
get back an ACK - but you should get back a Reset (RST) ..
So if your local SMTP server was running we'd expect to see
a connection. If it's not running we'd expect to get
You are getting neither - you are getting a timeout, which
means that the packet ( either your outbound request,
or the response ) is disappearing... and it's disappearing
quietly - so it's being dropped..
So I'm guessing at filtering rules - ipchains/iptables etc...
 It also sets the SYN flag too, but let's not worry about that.
