I followed this tutorial: http://postfix.state-of-mind.de/patrick ... rvers.html
Upon postfix reload, I get this:
postfix: Postfix is running with backwards-compatible default settings
postfix: See http://www.postfix.org/COMPATIBILITY_README.html
postfix: To disable backwards compatibility use "postconf compatibility_level=2" and "postfix reload"
postfix/postfix-script: fatal: the Postfix mail system is not running
When I try to sendmail, I get this error:
postdrop: warning: unable to look up public/pickup: No such file or directory
I am trying to bypass my isp's port 25 block. I am running Ubuntu server 16.
