Ubuntu Plesk and DKIM Setup

[Lloyd_mcse]

Hi guys,
I have a couple of questions on setting up DKIM on a Ubuntu 12.04.4 LTS Plesk 11.5.30 #29 server.
I use a little plain Ubuntu 12.04.4 LTS VPS setup (postfix/dovecot) for my personal domains and have DKIM running on there and from what I can tell installing OpenDKIM wouldn't interfere with Plesk, I'd just have to maintain it myself.
So my questions, am I missing something and has anyone else done it without issues?

Thanks in advance for your help/thoughts
Kind regards

Lloyd

Ok, well I've installed OpenDKIM and it's working great
However, now DomainKeys are not.
I'm getting this error..

postfix/cleanup[28162]: warning: milter inet:127.0.0.1:12768: can't read SMFIC_HEADER reply packet header: Success

Here's the milter section /etc/postfix/main.cf

# DKIM & DomainKeys
milter_default_action = accept
milter_protocol = 2
smtpd_milters = inet:127.0.0.1:12768,inet:127.0.0.1:12345
non_smtpd_milters = inet:127.0.0.1:12768,inet:127.0.0.1:12345

inet:127.0.0.1:12768 - DomainKeys
inet:127.0.0.1:12345 - DKIM

Any ideas?
Thanks for any input.
Regards

Do you have any cron tasks for pc-remote service which serves as Milter-server for Postfix? Check it with:

# crontab -l

Disable these tasks if they are exists.

Hi Igor,

I'm not sure why but DomainKeys still don't sign outgoing mail. Incoming mail is checked along with DKIM.
Any ideas?
Thanks in advance for any help

Had chance to have a fiddle with this, I changed the milter_protocol to 6 and all is good.

# DKIM & DomainKeys
milter_default_action = accept
milter_protocol = 6
smtpd_milters = inet:127.0.0.1:12768,inet:127.0.0.1:12345
non_smtpd_milters = inet:127.0.0.1:12768,inet:127.0.0.1:12345

==========================================================
Summary of Results
==========================================================
SPF check: pass
DomainKeys check: pass
DKIM check: pass
Sender-ID check: pass
SpamAssassin check: ham
==========================================================

Now, we just need more characters for TXT records so we can have 2048bit DKIM keys.
