Comments on Postfix with dkfilter (DomainKeys Implementation)

Postfix with dkfilter (DomainKeys Implementation) DomainKeys is an anti-spam software application in development at Yahoo that uses a form of public key cryptography to authenticate the sender's domain. dkfilter is an SMTP-proxy designed for Postfix. It implements DomainKeys message signing and verification. It comprises two separate filters, an "outbound" filter for signing outgoing email on port 587, and an "inbound" filter for verifying signatures of incoming email on port 25. This document is to describe step by step how to install dkfilter for postfix to deploy domainkeys signing and verification.

In section 4, you should modify /etc/postfix/master.cf, not /etc/postfix/main.cf

In addition to the ones you list, I had to install the following:

perl -MCPAN -e'CPAN::Shell->install("Net::Server")'

 Thanks for the docs, good stuff.

I had this error when installing OpenSSL::RSA (actually it's dependancy: OpenSSL::Random)

Random.xs:5:26: error: openssl/rand.h: No such file or directory

To solve it, I installed openssl-devel package, then tried again and it worked. I used "yum install openssl-devel", but whatever package installer you have should also be able to do that.

Also, I had trouble on installing Test::More, it errored out at "Test::Simple" dependancy, so I had to install "make" (yum install make), then download the source directly and install it manually: perl Makefile.PL, make, make test, make install.
