Hi, I have just installed RH9. I have configured sendmail and can send mail. However something is blocking port 25 for incoming mail. Just to check I completely disabled iptables and yet it is still blocked. I re-enabled iptables. The sever has two NIC's, one real world, one internal. If I try and telnet to localhost port 25 I get: 220 xxxxx.com ESMTP Sendmail n.nn.n/n.nn.n; Tue, 30 Dec 2003 22:15:53 +1000 If I try and telnet to the real world IP port 25 I get: Trying nnn.nnn.nnn.nnn... telnet: connect to address nnn.nnn.nnn.nnn: Connection refused What is blocking this port? a ps shows sendmail running: root 5091 0.0 0.4 5916 552 ? S 17:15 0:01 [sendmail] smmsp 5100 0.0 0.2 5716 308 ? S 17:15 0:00 [sendmail] This is the first time I have used RH9, what is the sm-client in the sendmail init file?
