Hi. I use ubuntu 8.10 server 64 bit + postfix + dkim-filter + dovecot There is a problem with dkim-filter. I followed the instruction at https://help.ubuntu.com/community/Postfix/dkim-milter Everything worked fine until I ran apt-get upgrade. The dkim-filter didn't work. When I sent mail, syslog said Code: ... Mar 19 16:40:57 myubuntu postfix/smtpd[6166]:warning: milter inet:127.0.0.1:8891: can't read SMFIC_OPTNEG reply packet header: Connection timed out Mar 19 16:40:57 myubuntu postfix/smtpd[6166]: warning: milter inet:127.0.0.1:8891:read error in initial handshake ... The mail is sent successful but without dkim's header. Hotmail just send my mail directly to the junk folder when I tried to restart dkim-filter the syslog said Code: ... Mar 19 06:31:18 myubuntu dkim-filter[14604]: can't configure DKIM library; continuing Mar 19 06:31:18 myubuntu dkim-filter[14604]: Sendmail DKIM Filter v2.6.0 starting (args: -x /etc/dkim-filter.conf -p local) ... After restarted dkim-filter. It ran normally but didn't work with postfix!?! any idea to fix dkim-filter? Thanks.

These are what I had tried - update dkim-filter2.6 to dkim-filter2.8 - bind dkim-filter's port from 8891 to 8892 - change milter_protocol in /etc/postfix/main.cf from 2 to 3,4,6 still no luck
yes, I tried. I don't know if my problem relate to Code: Mar 20 07:42:19 myubuntu deliver(root): mail_location not set and autodetection failed: Mail storage autodetection failed with home=/root Mar 20 07:42:19 myubuntu deliver(root): Fatal: Namespace initialization failed in /var/log/syslog which have appeared frequency. Nah,but I don't think "Namespace initialization failed" relate to dkim-filter
Someone has just posted a reply to your comment: http://www.howtoforge.com/quick-and...-ubuntu-postfix-and-dkim-filter#comment-11713 Maybe that helps.
I had the exact same problem. The cause (and solution) was that dkim does DNS lookups use TCP. Open your firewall to allow outbound TCP DNS queries (and allow the replies back in) and it should work. Martin
