UNIX configuration of outgoings SMTP relay on a UBUNTU 12.04 server. I do not need to receive email just send. The SMTP server will be mailgun. Once the configuraiton is complete I need to be able to send email from PHP scripts and from shell scripts. Once awarded I will provide admin logons to the server and the mailgun SMPT server credentials.
This is a simple configuration job for someone who knows this - I have tied but cant work it out.
