[exim] problem with exim

Hi,

Yesterday I install Exim on my FreeBSD 5.1

I start it.
when I type exim -odb localuser it deliver mail to mailbox
but when I type telnet localhost 25 I see:
/usr/local/etc/exim > telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 78-tor-7.acn.waw.pl ESMTP Exim 4.63 Sat, 16 Sep 2006 15:20:08 +0200
421 78-tor-7.acn.waw.pl lost input connection
Connection closed by foreign host.

What I do wrong?
