smtpd problem: can't send (relay) from remote hosts,
(not from hosts on LAN nor from outside LAN)
RedHat 7.0, sendmail 8.11.0-8
mail server on LAN ("myserver"),
behind ipchains firewall, portforwarding 25, 143, 110, 220
caching nameserver on firewall, 2 DNS registrations for external IP number
of firewall: user-x-y-z-w.ispname.com and
foo.dyndns.org
/etc/hosts on myserver:
127.0.0.1 localhost
192.168.1.221 myserver
192.168.1.1 myfirewall # internal LAN interface num of firewall
192.168.1.2 client-2 # ('Doze PC on LAN, Netscape Comm IMAP)
HOSTNAME of myserver: myserver
Made 1 change to /etc/sendmail.cf:
Djfoo.dyndns.org
sendmail started at boot, with contents of /etc/sysconfig/sendmail:
DAEMON=yes
QUEUE=1h
(Which according to documentation is supposed to be equivalent to
starting sendmail with -bd, which is supposed to be starting it as a daemon,
which means that smtpd feature is supposed to be active.)
I can send/receive mail from accounts directly logged into myserver.
I can read mail via IMAP with Netscape Communicator IMAP client from
mailbox on myserver
I cannot SEND mail from Netscape Comm client, with smtp server defined as:
192.168.1.2
(also if define as "myserver" with lmhosts.sam entry of 192.168.1.2 myserver)
The error message from Netscape client when try to send:
"There was no response. The server could be down or not responding"
I tried adding entry to /etc/mail/access
192.168.1.0 RELAY
(Restarting sendmail)
Makes no difference.
What do I need to do?
(Note: I will also want to run horde/imp webmail client)
