sendmail and imap-2002d
I am trying to setup a mail server but need a hand at the pop3 part.
info: Redhat 8 sendmail 8.12.9 imap-2002d I have it set up so on the server I can send and receive mail at mydomain.com but I cannot access mail through pop3. If I run outlook express on a 98 machine trying to access mail.mydomain.com it never finds the server and it errors out with The connection to the server has failed. Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E I think I must have something wrong with the pop3 part on the rh box. any tips The dns is running on another server.. but the mxrecord points mail.mydomain.com to the ip address of my new mail server. I can also ping the mail.mydomain.com server from the win98 box |
Can you do "ls -l /etc/xinetd.d/pop*" on the Red Hat machine?
Can you post the output of "netstat -n -l -t" on the Red Hat machine? |
ls
ls gives me
-rw-r--r-- 1 root root 335 Sep 1 2002 /etc/xinetd.d/pop3s |
netstat
netstat gives

(small mistake on my part) :
I should've asked : Can you do "ls -l /etc/xinetd.d/*pop3*" on the Red Hat machine? But that does not matter. Looking at the output of netstat on your machine I see the following line : tcp 0 0 192.168.0.132:110 0.0.0.0:* LISTEN so it looks like there's a pop3 server running on the Red Hat machine. (I assume 192.168.0.132 is your Red Hat Linux machine) What happens if you do : - "telnet <ip-address of Red Hat machine> 110" on the Red Hat machine. - "telnet <ip-address of Red Hat machine> 110" on the Windows machine. |
ok
If I stop the iptables I can get through.
I just need to figure out what to modify in the iptables so that qpopper can still be accessed by win98 pop3 clients. |
If you configured the firewall with the "redhat-config-securitylevel" tool, you should add a line like this to the "/etc/sysconfig/iptables" file :
-A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 110 --syn -j ACCEPT Or, if you used the iptables tool yourself, you can use the following command to allow connections to the POP3 port on your machine : "iptables -A INPUT -p tcp --sport 110 -j ACCEPT" |
