I am upgrading to postfix 3.9.0. I have not used DKIM in previous postfix installs, but I would like to start now with the new google rules. I have done some research and opendkim is the most recommended, however, other research states the opendkim has been abandoned by it's maintainers. So I am looking for a good alternative dkim software that will work with postfix that I can compile myself. I do not run on any linux version, so therefore I can not just apt-get a new dkim application. I run Solaris and therefore need to compile my applications, postfix and dkim. Any good suggestions will be appreciated.

I am super pleased with mailfromd! Running dkim for quite some time now.

I can remember looking at rspamd years ago. I thought it was a bit chaotic with all these rules. I can even remember asking developers some design questions which they could not answer. The fact that they generate their own graphs (still?) is also old fashioned. This Sergey that is working on mailfromd is an ace with mta's, even implemented for me an exporter endpoint, so now I can chart whatever I want.

I let rspamd do the DKIM (and DMARC-reporting) for me. It is actively maintained.
