Почему OpenDKIM не подписывает и не проверяет мои электронные письма? (CentOS 6.5, Postfix и OpenDKIM)

Я бегу:

CentOS 6.5
Postfix 2.6.6
opendkim: OpenDKIM Filter v2.9.0
    Compiled with OpenSSL 1.0.1e-fips 11 Feb 2013
    SMFI_VERSION 0x1000001
    libmilter version 1.0.1
    Supported signing algorithms:
        rsa-sha1
        rsa-sha256
    Supported canonicalization algorithms:
        relaxed
        simple
    Active code options:
        USE_DB
        USE_UNBOUND
    libopendkim 2.9.0:

Я установил Zarafa, и все работает отлично. Затем я попытался установить OpenDKIM, и у меня возникли проблемы. Я установил это на другой сервер, на котором работает Zimbra, и никаких проблем не возникло. Однако этот сервер не работает. Мой файл / var / log / maillog даже не показывает НИКАКИХ указаний на openDKIM. По opendkim вообще ничего не логируется.

Мои записи DNS добавлены правильно. (проверено через DIG) Я пробовал два разных файла конфигурации, но это текущий:

AutoRestart             Yes
AutoRestartRate         10/1h
LogWhy                  Yes
Syslog                  Yes
SyslogSuccess           Yes

Canonicalization        relaxed/simple

KeyTable                refile:/etc/opendkim/KeyTable
SigningTable            refile:/etc/opendkim/SigningTable
SignatureAlgorithm      rsa-sha256
Socket                  inet:8891@localhost
PidFile                 /var/run/opendkim/opendkim.pid

Вот / 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.
127.0.0.1
#host.example.com
#192.168.1.0/24
172.20.6.178
mydomain.com
zarafa.mydomain.com

РЕДАКТИРОВАТЬ: Кроме того, почему OpenDKIM не проверяет электронные письма? Когда я отправляю электронное письмо, я всегда получаю такие сообщения в моем журнале:

25 октября 21:13:32 zarafa postfix / smtp [7201]: ошибка проверки сертификата для megawatt.resistor.net [208.69.177.116]: 25: ненадежный эмитент / C = US / ST = New York / L = Brooklyn / O = Eland Systems / OU = Eland CA/CN=Eland/emailAddress=sm@elandsys.com

И не имеет значения, куда я отправляю сообщение. Я отправил его себе на сервер, который, как я ЗНАЮ, проходит проверку DKIM, и я все еще получаю его.
