libopendkim 2.9.0:
I've installed Zarafa and everythign is running perfectly. I then tried to install OpenDKIM and have been having trouble. I installed this on another server I have running Zimbra and there were no problems at all. This server is not cooperating though. My /var/log/maillog file is not even showing ANY indications of openDKIM. Nothing is logging at all regarding opendkim.
My DNS records are properly added. (tested via DIG) I've tried two different config files but this is the current one:
AutoRestart Yes
AutoRestartRate 10/1h
LogWhy Yes
Syslog Yes
SyslogSuccess Yes
Mode s
Canonicalization relaxed/simple
ExternalIgnoreList refile:/etc/opendkim/TrustedHosts
InternalHosts refile:/etc/opendkim/TrustedHosts
KeyTable refile:/etc/opendkim/KeyTable

Here is /etc/opendkim/SigningTable:
# OPENDKIM SIGNING TABLE
# This table controls how to apply one or more signatures to outgoing messages based
# on the address found in the From: header field. In simple terms, this tells
# OpenDKIM "how" to apply your keys.
# To use this file, uncomment the SigningTable option in /etc/opendkim.conf,
# then uncomment one of the usage examples below and replace example.com with your
# domain name, then restart OpenDKIM.
# WILDCARD EXAMPLE
# Enables signing for any address on the listed domain(s), but will work only if
# "refile:/etc/opendkim/SigningTable" is included in /etc/opendkim.conf.
# Create additional lines for additional domains.
#*@example.com default._domainkey.example.com
# NON-WILDCARD EXAMPLE
# If "file:" (instead of "refile:") is specified in /etc/opendkim.conf, then
# wildcards will not work. Instead, full user@host is checked first, then simply host,
# then user@.domain (with all superdomains checked in sequence, so "foo.example.com"
# would first check "user@foo.example.com", then "user@.example.com", then "user@.com"),
# then .domain, then user@*, and finally *. See the opendkim.conf(5) man page under
# "SigningTable" for more details.
#example.com default._domainkey.example.com
*@mydomain.com dk_default._domainkey.mydomain.com
Here is /etc/opendkim/KeyTable:
# OPENDKIM KEY TABLE
# To use this file, uncomment the #KeyTable option in /etc/opendkim.conf,
# then uncomment the following line and replace example.com with your domain
# name, then restart OpenDKIM. Additional keys may be added on separate lines.
#default._domainkey.example.com example.comefault:/etc/opendkim/keys/default.private
dk_default._domainkey.mydomain.com mydomain.comk_default:/etc/opendkim/keys/mydomain.com/dk_default
Here is /etc/opendkim/TrustedHosts:
# OPENDKIM TRUSTED HOSTS
# To use this file, uncomment the #ExternalIgnoreList and/or the #InternalHosts
# option in /etc/opendkim.conf then restart OpenDKIM. Additional hosts
# may be added on separate lines (IP addresses, hostnames, or CIDR ranges).
# The localhost IP (127.0.0.1) should always be the first entry in this file.

EDIT: Also, Why is OpenDKIM not verifying emails? When I send an email, I am always getting messages back in my log like this:
Oct 25 21:13:32 zarafa postfix/smtp[7201]: certificate verification failed for megawatt.resistor.net[208.69.177.116]:25: untrusted issuer /C=US/ST=New York/L=Brooklyn/O=Eland Systems/OU=Eland CA/CN=Eland/emailAddress=sm@elandsys.com
And, it doesn't matter where I send the message to. I've sent it to myself on a server that I KNOW is passing DKIM verification and I'm still getting it.
