Sendmail and incoming connections
I am trying to connect to sendmail 8.12.5 running on a RH9 box. Sendmail is running and i can connect like
[root@goran /]# telnet localhost 25
from the machine that sendmail is on, but not like
[root@goran /]# telnet 192.168.1.55 25
or by using the domain name (I am running a name server) from the machine that sendmail is on, or from another machine.
This is not a firewall issue, as the local firewall has been turned off. I can connect to the machine via ssh and smb.
Is there some sort of other option that sendmail uses to reject connections, or maybe some thing I could put in hosts.*? The hosts files are empty right now.
Thanks in advance for your help.
