How to create Postfix database files

Every time I come to recreate the Postfix database file when I edit the file /etc/postfix/ I forget what command I need to recreate

Hopefully I’ll check my blog next time. The command is postmap. Hope this is useful for someone else too!

postmap /etc/postfix/
/etc/init.d/postfix restart

  1. It gets me every time too. I sit there thinking that I know I have to rebuild the hash files but I can never remember the command – probably because of its name, which although technically correct in that its to do with postfix map files, isn’t that obvious.

    1. Me too. I stared at the command prompt thinking it was “hash” something or other. It’s actually not that easy to find an answer either. I had to check more than a page or two to find postmap.

      Not anymore eh? 🙂

  2. I always forget this too… My solution was to just put a comment at the top of my file:

    # postmap /etc/postfix/ && /etc/init.d/postfix restart

    So when I’ve finished editing, copy that line, save the file, paste onto the prompt… You don’t even have to look at your blog, it just there waiting for you!! 🙂

  3. How the hell am I supposed to remember the address for this blog next time I forget the same command? Some 5th or 6th googleing led me here.
    But thanks anyway. At least you helped me this time.

  4. make is your friend:

         /etc/init.d/postfix reload

    After edit, run make in /etc/postfix. Add extra targets as desired.
    NOTE: make sure those indents are TABS, not spaces! Makefile 101!
