Ubuntu postfix error — postdrop: warning: unable to look up public/pickup: No such file or directory

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

Thanks so much! I unknowingly had sendmail and postfix running together and it’s been a frustrating couple hours trying to figure out why mail wasn’t sending!

For those with the same problem who come across this, be sure and do “kill [process number]” when running the commands above.

Thank you this helped.

Though in my case it was only nessarily to be sure sendmail was stopped. Apparently uninstalling it doesn’t stop it.
