Maybe you should hide/mask your public ips (and mail addresses) on a forum, especially if running mail servers, we never know
So the postfix configuration directory for the 2nd server is /etc/postfix-xx.xxx.162.12 How did you start the 2nd server, like this? postfix -c /etc/postfix-xx.xxx.162.12 |
Thanks for your suggestions keefaz
when i install the postfix by using yum install postfix then its automatically postfix directory created in /etc/postfix and next i changed the some information in main.cf and master.cf like this myhostname = host.xxxxxxx.com mydomain = xxxxx.com myorigin = $mydomain inet_interfaces = xxxxxx.com mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mynetworks = xx.xx.xx.96/28, 127.0.0.0/8 in master.cf xx.xx.xx.96:2525 inet n - n - - smtpd after that cp -rp /etc/postfix /etc/postfix-xx.xx.xx.12 then another one folder(postfix-xx.xx.xx.12) are created in /etc then i changed information in main.cf and master.cf postfix -c /etc/postfix2 reload |
But /etc/postfix2 exists?
Did you try: postfix -c /etc/postfix-xx.xx.xx.12 Also did you try disabling the firewall just the time to test telnet info.x.x 2525 |
EDIT: sorry, I [Newbie] didn't see all the new posts when I wrote this,
so this may ALL be irrelevant. Quote:
(yet it responds to port 25) (try telnet ...12 25) **I don't know postfix, so I don't know how master.cf works. There also MIGHT be a basic netmask issue: (again, I'm not sure) ifconfig says 255.255.255.0 which is not /28 (in postfix configS) Post netstat -rn; netstat -nlp | grep 25 In addition to the [extreme] debugging technique of strace, I'm wondering if there is a way to 'trace' the relevant net pkts... (I assume all the telnet cmds are being run on the [postfix server] host itself...) |
netstat -nlp | grep 25

Now, nothing appears to be listening on 2525!
Check ( with ps -ax) to see that the second is running. Then use strace -p ... to see what it's doing. Can you try running *only* the second one (without the 1st running) & telnet to it (both 25 and 2525)... (I'm not sure how to tell if the netmask might be a problem; hopefully another LQ'er can comment on this. i.e., is the mynetworks.../28 ok? Also, shouldn't the 1st's master.cf have 25, not 2525?) By any chance, did you actually want/need all three eth0 to be /28? |
@Jjanel, you're right on network mask, xx.xx.xx.96/28 excludes xx.xx.xx.96 from the IPs range, but next setting 127.0.0.0/8 allows it from local
|
@Jjanel
i was run the second instance with port 25 and 2525 still in telnet its shows connection refused in second instance(main.cf) my entry is mynetworks = xx.xx.xx.12/28, 127.0.0.0/8 is this correct? |
guys
both postfix instance working fine here is the status postfix/postfix-script: the Postfix mail system is running: PID: 10860 postfix-xx.xx.xx.12/postfix-script: the Postfix mail system is running: PID: 10943 i think this is port issues because in netstat -nlp| grep 25 its showing only one ip address port i.e first ip address second one is not showing can you please tell me how to enable the port on selective ip address |
It's in master.cf file in /etc/postfix-xx.xx.xx.12
<IP>:<Port Number> Could you change mynetworks in main.cf in /etc/postfix-xx.xx.xx.12 and keep only local subnet, just to test mynetworks = 127.0.0.0/8 |
i assigned the mynetworks = 127.0.0.0/8 in main.cf in /etc/postfix-xx.xx.xx.12
but still its doent showing anything [root@I ~]# netstat -nlp | grep 25 tcp 0 0 xx.xx.xx.96:25 0.0.0.0:* LISTEN 11923/master unix 2 [ ACC ] STREAM LISTENING 12562 1/systemd /var/run/dbus/system_bus_socket [root@I ~]# telnet info.xxxxx.in 25 Trying xx.xx.xx.12... telnet: connect to address xx.xx.xx.12: Connection refused how to restart the second postfix instance? service postfix restart ..it will applied for only default postfix |
you can always start it manually (without service command)
# postfix -c /etc/postfix-xx.xx.xx.12 |
postfix -c /etc/postfix-xx.xx.xx.12
postfix-xx.xx.xx.12/postfix-script: error: unknown command: '' postfix-xx.xx.xx.12/postfix-script: fatal: usage: postfix start (or stop, reload, abort, flush, check, status, set-permissions, upgrade-configuration) |
mmh, maybe: postfix -c /etc/postfix-xx.xx.xx.12 start
