Mailing list changes -- please read, impacts how you use the list!
We were made aware of some issues with inadvertent unsubs from the mailing lists. To fix this we were forced to go full on with DMARC, DKIM, SPF, ARC, the whole enchilada. This will impact you, the user, in a very important way: the From: address in the header of emails you get from the mailing lists will now be from @muug.ca. Previously, they would be From: the actual person who sent the email to the list. (Look at the From: header and Reply-To: header of this email to get an idea of the change.) This will impact what happens when you press REPLY (and related buttons) in your MUA (your Outlook, gmail, thunderbird, etc). What exactly happens is up to your MUA. But now you have to be extra careful that you aren't sending a private/personal response (meant for the human sender) to the mailing list. Always check your To: and Cc: headers before you hit send! The opposite may happen too, a reply you want to go to the list may just go to the sender! Click your reply, reply-all and reply-sender buttons now to get a feel for what will happen (then hit cancel!). On my box/MUA, the reply-sender button is now useless (completely backwards). YMMV If you're interested in the full technical spiel feel free to ask me at the next meeting's roundtable! :-) If something doesn't work, email (right away!) the list, or email me directly with MUUG in the subject. (See this email's reply-to header.)
Apologies, one setting wasn't tweaked on roundtable, causing the reply-to to be incorrect on my last email. If looking at the headers or running your reply-button tests, please use this email instead.
Thanks very much for the detailed explanations Trevor. Replying to this message to thank you as well as to test my MUA. FWIW I use iCloud email with thunderbird on OpenBSD, and Apple Mail client on all Apple devices. Vijay Sent from my iPhone

Seems like Thunderbird is doing excellent sane choices for list replies: On Thunderbird (140.9.1esr): - *Reply_to_Sender_Only [Ctrl-R]:* replies to the "Reply-To" header (Trevor). Sane. - *Reply_to_All [Ctrl-Shift-R]:* replies to both "Reply-To" and "From" headers (Trevor and Roundtable). Sane. - *Reply_to_List [Ctrl-Shift-L]:* replies to the "List-Post:" header (Roundtable). /*I didn't even know Thunderbird had this option until now!*/ Thanks for all your hard work on the mailing list Trevor. By the power vested in me as your MUUG treasurer, /*4 hero cookies for you!*/ -- Bradford C. Vokey Treasurer Manitoba UNIX User Group On 2026-04-18 6:52 a.m., Trevor Cordes via Roundtable wrote:

Thks Trevor for the detailed procedural headsup! And as a much ongoing satisfied WordStar user over all others known to me, special further thanks to Brad for providing the keystroke variations to no longer have to lose key-board etiquette to use the multi-step mouse function reach when but simple memorable keystroke functions are available. Please note in this instance as inteaded *[Ctrl-Shift-R] ie. **Reply_to_All added all three* In short, thanks for spelling them out. I have several email addresses and only download when I choose to do so. Re TB Is there a way to auto-select a shorter list of at least two or more to fetch emails, instead of all of them? As a nerdie inconvenience, TB also knows, but only sometime if one is offline and asks to go online. But most times after first use, when one is offline as asks to fetch emails does not do so nor provides any feed-back. An easy way to smarten TB up?

I just did the same 3 tests using my *Fastmail*, and the results were the same/sane as Bradford's results below. That is to be expected, because the two chief designers at *Fastmail* are also two of the chief architects of the JMAP initiative, an IETF standard intended to ultimately replace IMAP.
