The 25-port problem

Hello,

An external telnet (which is running on a Windows system) fails to the port
25 of another machine running under OpenBSD. A few services installed on the
latter, including www, ftp and pop3, - everything work fine, except when
connecting to the port. I've googled for the problem and found that there is
a need to edit a rc.conf file, sendmail_flag option. Either to remove the
reference to the localhost.rc file or to replace it with the sendmail.cf
file. The problem is that it still doesn't work.

Also, note is that there is no ISPs between the Windows and OpenBSD
machines, so it is definitely not because of port blocking or something like
this.

Could anyone suggest something?

Thank you.

Is sendmail listening on an ip other than localhost? Do you have something
like "DAEMON_OPTIONS(`Name=IPv4, Addr=192.168.0.1 Family=inet')"?
