SMTP settings not show in the Admin --> Emails Tab
You don't need to install anything! Simply go to Admin Panel > Emails tab and enter SMTP info for each of the addresses you want configured.
I have installed OsTicket 1.7RC4 and the installation did not give me any warning or error so I am assuming all went right.
But I do not see the options that you have mentioned.
I am using Ubuntu 12.04 and have the LAMP stack installed.
I am attaching a screenshot of my emails tab to this reply.
Please suggest if I am missing a step.
