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

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
