You have ident enabled in /etc/inetd.conf


from
http://www.nmr.mgh.harvard.edu/MGH-UNIX/ident.html

It is frequently useful for a server to identify who is trying to use it. Two examples are the FTP daemon, and the Sendmail daemon. If you run an anonymous FTP server, users are asked to give their email address as their `password', but this isn't verified. Modern FTP daemons can be configured to ask the user's system for the user name of the person who made the connection. Sendmail does a similar thing: modern versions will ask the system sending mail who is really sending it, and will put that information into the headers, if it can obtain it. These cases, and others, make it much easier to figure out who is using such services, IF the foreign machine is running the daemon which answers the servers. The remainder of this page tells how to install an IDENT daemon on your system. (This allows other servers to find out which of your users is connecting to them.)

I am new to Solaris, is this a good thing or should I stop it?  This box is running sendmail so I imagine that it is the sendmail sending out.

simply comment the ident line out of /etc/inetd.conf and then restart inetd
pkill -1 inetd (Solaris 8 / 9)
or
kill -1 `ps -ef | grep [iI]netd |awk '{print $1}'`   (Solaris 2.6 or older)
