I've bought an unmanaged dedicated server. Mainly to help me learn.
My email isn't working and the host support have told me I that need to open port 25 to enable smtp. Note I can't send or receive email.
I've used SSH to login and I've tried a few of the sample snippets of code from this forum but I just get a command not found back.
My server is running centOS and it has a Plesk GUI.
I've connected to the server using ssh root@myipaddress
