How to config mailbox openpaas?

I’m looking for a solution to replace Exchange 2010, we have 1500 mails. Openpaas seems to me a viable solution, I’m trying to test it, but during the installation I encounter a lot of problem for the setup. I do not find a lot of tutorials to help me.
I have install Openpaas on a Debians 8.11, the server part works well, I am now on the Web Part.
I would like to config my Openpaas to receive and send mails, how should I do?
Are there any other information to set up?
Are there any tutorials?
Thank you in advance for your help.

I too trying to figure out, how to enable James(SMTP)

After installation I connected to OpenPaas Webportal as administrator, and specify localhost DNS( as smtp server, even restarted all service that listed in documenation
systemctl restart {mongod,elasticsearch,cassandra,redis,rabbitmq-server,php-fpm,nginx,james,openpaas}
But SMTP seems not enabled and I am not able to access James webadmin portal.

Please help

Hi Chan
Sorry for late answering.
Had you tried with the Gettings Started?
To make sure all services are started and enabled on boot, run the following commands as root:

systemctl status {mongod,elasticsearch,cassandra,redis-server,rabbitmq-server,nginx,james,openpaas}

yes i use the Gettings Started to config Openpaas.

this commands is lauch and all services is ok

Please select Administration module -> Mail
Config Transport type as SMTP
Host to your host. Port: 1025.
You can test with Mail Server test at the bottom of this page.


Please check SMTP port available on James server by telnet in SMTP port (default 25)


This is same with Comment configurer le smtp et pop de openpaas?. We will focus in one.

i have test the port 1025 and anything
i try to test port 25 by Telnet and anything
when i lauch the command netstat -ant, i dont see the port 25 and 1025
i dont know how to open these ports, because i have to test the commande :
iptables -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT
iptables -A OUTPUT -p tcp -m tcp --dport 25 -j ACCEPT
and the commande :
iptables -t filter -A INPUT -p tcp --dport 25 -j ACCEPT

when i lauch the commande netstat -ant, i dont see the port 25

I too see same problem, following same documentation and even disable firewalld.
But the result is same none of the james port will get open.
