Hi, i have a CentOS 4.4 running sendmail, with two network interfaces (eth0 -> Internet , and eth1 Local Network), from the terminal (SSH) i do

telnet 127.0.0.1 25

and it connects to sendmail (i think so), but

from another server (external, and so from the same SSH terminal) i try to connect to the Internet IP

telnet 146.77.220.236 25 Trying 146.77.220.236... telnet: connect to address 164.77.228.236: Connection refused telnet: Unable to connect to remote host: Connection refused

so i was thinking "it could be the fu...ing IPTABLES"

from terminal execute

iptables -L| grep smtp

and the result is:

ACCEPT tcp -- anywhere anywhere tcp dpt:smtp

so , if the sendmail service is up, what could be happen??

sendmail by default - for security - doesnt listen on the external interface.

You need to modify /etc/mail/sendmail.mc to say :-

DAEMON_OPTIONS(`Port=smtp, Address=146.77.220.236, Name=MTA')dnl

as well as the line that says 127.0.0.1 (if you want it listening on localhost)

Then run 'make' in the /etc/mail directory and restart sendmail.

Regards Lance
