I installed postfix and got this error: postdrop: warning: unable to look up public/pickup: No such file or directory. Turns out that sendmail was previously installed and that was messing things up. I had to stop sendmail and make the appropriate directory and restart postfix. Specifically: mkfifo /var/spool/postfix/public/pickup ps aux | grep mail kill  sudo /etc/init.d/postfix restart Test emailing  #email youremail@abc.com (enter) subject: test (enter) test (ctrl+d) cc: youremail@abc.com (enter) if your receive above then email everything is fine now! :)
