Is this a telnet connection? Is so can some break it down for me. I have telnet turned off.

What makes you think it was a telnet connection. telnet uses port 23. This was for port 25, SMTP.

Cheers,

This is a line logged by identd about user with uidnumber 25: the smtp user (which is managing your mail queue). The other side asked your identd about the identity of user number 25 and it replied with a harmless message i.e. it told nothing of value.
However you might want to turn identd off if you don't want any information about your box to leak onto the internet.
