I have to use a server where its operative system is Ubuntu version 12.10.
I use an application on that server via browser and with that application I would be able to send emails.
I would like to know if my server must recognize the SSMTP command in order to send emails or if this command it's not necessary because it works only by shell command.
Everytime I try to connect to my server at port 25 it refuse my connection because there isn't any process assigned in that port.
Can you help me?
