Thanks for this write-up. I used OpenDKIM on my CentOS setup, and wrote about it here.

Good tutorial, thanks! Couple things I ran into:
1. I had to put the INPUT_MAIL_FILTER into sendmail.mc, not submit.mc. Sendmail was not communicating w/ dkim-milter at all until I did this.
2. I see no mention of ADSP. Your readers can go here: http://www.sendmail.org/dkim/tools to help set this up.

[...] probably the goal I am most satisfied with. I find myself referring back to my own posts (e.x. on how to setup DKIM on Centos, or how to implement semantic naming in CSS), which I think is an indication that what I write has [...]

Great, thanks.

Hi, it’s a mistake in my post, the “Signature default” part should not be there (there is no Signature parameter). Fixed this in the post.

So try removing that line.

See man dkim-filter.conf for the actual options.

I’ve used this:
Canonicalization simple
Domain mydomain.com
KeyFile /etc/dkim-milter/default
Selector mail
Signature default
SignatureAlgorithm rsa-sha256
Socket inet:8891@localhost
Syslog Yes
Userid dkim-milter
SubDomains Yes
SyslogSuccess Yes
X-Header Yes

but it says:
Starting DomainKeys Identified Mail Milter (dkim-filter): dkim-filter: /etc/mail/dkim-milter/dkim-filter.conf: configuration error at line 5: unrecognized parameter

The selector name is “default”.

Do you know what’s wrong?
