Re: This mailing list breaks DKIM

It has been brought to my attention that all my mail to the OCLUG
list is being spam-binned by Google.

The reason is that I use DKIM on all my outgoing mail, and the OCLUG
mailing list software breaks DKIM.  I believe I've brought this up
before.  Scott, can you please fix it?

Hi Dianne,

I understand, as I have the same problem. You should see all the individual DMARC failure reports I get every time I mail to the ISC BIND list with my DKIM-signed messages!

I have talked with Scott about this last month. We were also having issues on the board email list.

I looked into it and the current email list SW, ezmlm cannot handle DKIM properly. Did I tell you I am not a fan of anything with "easy" or "EZ" in the name? "Easy to use" is easy to say.

We are going to have to change list SW to fix this. Mailman is significantly more complicated to configure but handles DKIM, and also ARC, which Google does use. They were involved with the development of ARC. https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/handlers/docs/arc_sign.html

We have been really personally busy the past while, Scott especially so. Fixing this very real problem is on my "do soon" list within the next week though. It needs some time to properly configure and test, NOT on this list obviously.

It is a problem, so thanks again for raising this. I hope maybe you can use an alternate email address in the short term until I can get to this?

cheers,

Brett

The issue is well-described at https://doc.coker.com.au/internet/dkim-and-mailing-lists/
