Will DKIM reduce the spam score

[Merlin <ng...@fastmail.fm>]

Hi there,

I am looking into DKIM in order to make it more easy for e-mail
providers
to verify my server adress and therefore get a trustworthy spam score
like "ALL_TRUSTED",
or "BAYES_00".

Do you believe that adding DKIM support for postfix will help? I looked
into the postfix help on
how to achieve that:
http://www.postfix.org/MILTER_README.html

Unfortunatelly that would meen that I would have to upgrade from 2.2.1
which I would rather like
to not touch.

I am not even sure if it would help. My situation is, that I am running
a community page that
sends for example opt-in registration emails to verify e-mail adresses
on sign-ups. Some e-mail providers
seem to mark that as untrusted, or even spam with a score of 0-3.5. I
would like to make sure all
e-mail got delivered and do search therefore for ways to add signatures
or similar to set myself apart from
spammers.

Thank you for any hint on how to proceed from here.

Best regards,

Merlin

Merlin:
I have a couple of -very- old Postfix 2.1.5 mail servers up and
running with DKIM signing support. How did I achieve that? by means of
Amavisd-new and DKIM-Proxy. Basically, I route every mail originated
at my server (e.g, via webmail, OR TLS-authenticated users) to a
different Amavis stanza, and then I make DKIM-Proxy sign outgoing
messages. You can find more info at Amavis site and DKIM Proxy
(http://home.messiah.edu/~jlong/dkimproxy/) sites.

If you want more info, I have written a HOWTO, but is in Spanish,
tough the main concepts can be easily grabbed.
