Why doesn't sendmail wait to receive on port 25?

[tomohito.kajiwara at nts.ricoh.co.jp]

I'm trying to install sendmail8.13.4 into freeBSD 6.0.

And I done all setting of sendmail and confirmed that sendmail is running.
in addtion of that. I confirmed that sendmail is working as the followings:
1. I can send e-mail by "telnet localhost smtp"
2. I cannot connect to this PC at any another PC by "telnet IPadress smtp".
And I found out that the PC I am installing does not wait to receive on
port 25.
