dkim-filter problem - can't read SMFIC_OPTNEG reply packet header

[leonhongkong]

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
...
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
...
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 :confused:

Have you tried to restart dkim-filter (or reboot the whole system)?

Have you tried to restart dkim-filter (or reboot the whole system)?
yes, I tried.

I don't know if my problem relate to

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
:confused:
