I know this has been asked a hundred times. But I've done a lot of Google searching without success. My question: I want to log every activity of my postfix server. Neither the default file /var/log/mail nor any other concerning mail or postfix exists.

  1. What's the exact string to put into the configuration file /etc/postfx/main.cf to enable logging?
  2. Where can i see which configuration file postfix uses? (according to my hint below)

Thanks for your answers.

Hint: I use postfix together with dovecot. I installed meta package some months ago.
