    Hi everybody,

    I've followed almost every instruction from many websites (including HowToForge) to install DKFILTER on my postfix. I've spent 24+ hours reformatting and reinstalling everything. I still can't get my DKFILTER to work.

    I have checked my DNS TXT records online, and they seem to be fine. The problem is that when I view Maillogs, I see:

    Mar 17 01:12:27 schoogo postfix/postfix-script: fatal: the Postfix mail system is not running

    Mar 17 01:14:20 schoogo postfix/postfix-script: fatal: the Postfix mail system is not running
    I don't even see DKFILTER in my maillog anywhere!
    Of course, my outbound emails don't get signed. But they do get delivered.

    My DKFILTER process is running. I checked by typing "ps aux".
    I've also tried adding the pickup line in another manual:
    pickup fifo n - n 60 1 pickup
    -o content_filter=dksign:

    I am sending these emails through PHP mail() function.
    The PHP.ini configuration for sendmail is:
    sendmail_path = /usr/sbin/sendmail -t -i

    Also, I do not have TLS or SMTP-AUTH enabled, as I heard that these conflict with domainkeys.

    I installed DKFILTER but it doesn't seem to work. Could it be that my sendmail is still getting in the way? Can anyone find out what's going on for me?

    Thank you so much!

    Note: I did not install dk-MILTER. What does this mean? Do I need that?

    HI falko, thank you for your reply.

    I've reformmatted my system yet again, and now I tried to install Domainkeys using the tutorial TopDog wrote.

    I got domainkey to sign, but the problem is that it's not "right" for some reason.
