I have a fresh DokuWiki installed on an Ubuntu 16.04 server VM.
The VM is already configured to send system email via a smarthost relay, through Postfix.
I cannot, however, get DokuWiki to successfully send any email. Likely PHP is not using the system's Postfix configuration.
Can I make DokuWiki send by just invoking /usr/bin/mail ?
If not, how do I tell DokuWiki (PHP?) to send via my smarthost relay?
I've googled this and searched forums but not finding anything useful yet. Most results are how to use sendmail, but that's not what I have.
