I imagine when port 25 stops giving 5xx failure message back, mail reception might improve. ^_^;
Works fine for me, your getting an error because your trying to send a command before receiving the first 220, aka RFC violation. As long as you connect, wait a moment without trying to send a command, your fine. telnet 219.90.94.56 25 Trying 219.90.94.56... Connected to static-host-219-90-94-56.tri.ph.
