Stephen, Thanks for your reply. I am replying directly to your email as I didn't see your reply in the threads of my original post.
My guess is that you are not getting complaints because it is just recently that the big name email servers (gmail, yahoo, icloud, microsoft) have just recently started enforcing the DKIM standard and what makes it worse is that they all seem to be taking different approaches to that enforcement. Could also be that most of the mailman users are using mailman 3.xx - but unfortunately CPANEL does not support that version - they recently let me know that they are going to continue to support mailman 2.xx even though it is no longer being maintained by python so hopefully we can get them involved in finding a solution. In my environment (WHM/CPANEL) mailman version 2.1.39 is not DKIM signing the mailman emails. All other emails that my domains send out are being DKIM signed - so it looks like EXIM is doing it's job on all outgoing mail except that being sent by mailman ... I have added you to a mailing list on my test server and will send a message out. You will see that it does not have a DKIM signature from the domain that is sending the emails out - that is if you get the email at all - I can see if your email server rejects the email - but if it does I can not see if it actually makes it to your inbox . I will send you a separate email letting you know that I sent a message thru the mailing list - so if it does not make it to your inbox you can check your spam/junk folder. My VPS is OS Alma Lunix 9.x on which I installed WHM/CPANEL (124.0.23), CloudLinux 9.5 and Imunify 360. So i just sent out a message via a mailman list (memb...@template.missoucimasternaturalists.org <mailto:memb...@template.missoucimasternaturalists.org>) - lets see if you get it. My server tells me it made it to your email server and was accepted. JerryB > On Jan 27, 2025, at 8:40 AM, Stephen J.
