I have created  new instance of postfix as postfix-2 using postmulti command ,I have edited the master.conf of instance postfix-2 to open port 855 for smtp.But still unable to see or connect to open port 855.

Please fins main.cf and master for main instance and postfix-1 in attachement.

here are the steps which i did to create 2nd instance.

# postmulti -e init
# postmulti -I postfix-2 -e create

My requirement is to tun bot instances separately eg. 1st instance runs on port 25 and 2nd runs on port 855



 main-postfix.txt main-postfix.txt master-postfix.txt main-postfix-2.txt master-postfix-2.txt

From where are you connecting to this port 855? Because in the master-postfix-2 file that instance is told to only listen on localhost.

Could you run this command and paste the output here?
netstat -tlnp|grep master

here is the output you have asked for  :

tcp        0      0 127.0.0.1:10024         0.0.0.0:*               LISTEN      903/amavisd (master
tcp        0      0 0.0.0.0:855             0.0.0.0:*               LISTEN      14417/master    
tcp        0      0 0.0.0.0:825             0.0.0.0:*               LISTEN      1448/master    

Its working Thanks Buddy

root@mail:/etc/postfix-2# telnet 10.0.0.185 855
Trying 10.0.0.185...
Connected to 10.0.0.185.
Escape character is '^]'.
220 mail.localdomain ESMTP Postfix (@@DISTRO@@)


but i was confused due to nmap output , it didnt show 855 open

22/tcp    open  ssh
25/tcp    open  smtp
80/tcp    open  http
110/tcp   open  pop3
143/tcp   open  imap
993/tcp   open  imaps
995/tcp   open  pop3s
3306/tcp  open  mysql
10024/tcp open  unknown


Anyways thanks for clearing my confusion
