Port 25 is not the telnet port. It is the SMTP port, and what you're getting is the response from the SMTP server — as you say, "still the SMTP listens".
When you are using the
telnetclient this way, you are not actually using the telnet protocol. You're using the same command, but conveniently, unless you connect to something that starts sending the special telnet control character (0xFF in hex), it effectively acts like a raw TCP connection. (Give or take some technical quibbles — if the quibbles matter, usenetcatinstead oftelnet.) And then, if you like, since SMTP is a simple protocol, you can type SMTP commands and pretend you are a mail program. (This can be quite useful for testing.)So, basically, if you want this to stop, turn off SMTP. Otherwise, don't worry about it.
