I'm a novice when it comes to server admin, and I need some help. I recently got sick of GoDaddy, and I signed up for an unmanaged rackspace server. I'm running a Debian instance, and I'd like to set up the server to send outgoing email via PHP and via cron.
PHP and Apache are already installed. I've installed sendmail, via apt. I have no idea how to set any of this up. I don't really need inbound support, although I imagine it would be nice for my PHP emails. (Or I can just have
sendmail() change the return address in my PHP script.)
Specifically, I have no idea how to configure sendmail as an outgoing mail server. How would I do that?
