Remembering how I setup my email server couple years ago, I try to write it down. Thankfully, I write all commands and configuration when setting it up using awwan.

Email server using #postfix, #opendkim, and #dovecot .

#sysadmin

Added a guide on how to set up #postfix with #opendkim so that you can send your own (signed) emails instead of using an external service such as sendgrid.

Blueonyx now supports OpenDKIM out of the box:

Hey #infosecPeople & #postmaster & #emailExperts what would be the best (as more stable/safe/RFC-compliant…) #DMARC filter for #postfix ? (inbound, obviously)

Until recently I was using policyd-spf as a policy service + #openDKIM & #openDMARC as milters and now I've disabled policyd-spf to do #SPF checking inside openDMARC.
I'm contemplating the idea of switching to Fastmail's authentication_milter but it looks like a very high maintenance piece of software.
Tell me about your choice(s)!

Anyone familiar with #opendkim? Tried to set it up on my server and I'm getting 451 errors whenever I try to send an email.

After spending too much time trying to get Opendkim working with non-chrooted Postfix, I just gave up on getting this two programs to talk over the socket and followed this guide to get them to talk over a port.

This is not ideal, but at least got it to work.
