Hi Hugh, Hi all,
Okay this is not a RADIUS question, but excuse
me anyway.
I have a RedHat 6.2 Linux system that has been
configured as a mail server
for a real Internet domain. Users can receive their
mails but nothing (mails) can be sent out.
After a lot of troubleshooting I made out the
following:
1. The system can't send mails out because you
cannot initiate a telnet session from it
to any other system on port
25 e.g.,
[root@mail itayemi]# telnet 10.0.4.4
25
Trying 10.0.4.4... telnet: Unable to connect to remote host: No route to host This is the same message that keeps being written
to the mail log (/var/log/maillog)
by sendmail. Any ideas?
You can telnet to it on port 25 from other
systems.
I have looked at all the common causes I can think
of (DNS, inetd, routing, sendmail etc)
Nothing seems to work. The system is not configured
as a firewall and the port is not blocked
by the router or any other device.
Regards,
Tunde I.
