Thanks for that link. I think you are on to the right track, although
I am still not sure how to fix things. I look at the messages that I
cannot reply to, and there are dkim errors. But I can post fresh
messages to those lists.
Here is the offending header, from lists.wpirg.org (which is hosted by
Authentication-Results: mta1596.mail.gq1.yahoo.com from=lists.wpirg.org; domainkeys=neutral (no sig); from=yahoo.ca; dkim=permerror (bad sig)
It's the "dkim=permerror" that is causing the issue.
Here is a message I sent to kwlug-disc (also hosted by CCj/Clearline):
Authentication-Results: mta1510.mail.ne1.yahoo.com from=kwlug.org; domainkeys=neutral (no sig); from=yahoo.ca; dkim=neutral (no sig)
I can see that other people sending to the garden list are producing
messages with "dkim=permerror" as well (eg from Gmail). This is also
affecting other messages on this server (fvc-wat-announce,
discuss at kwartzlab, rainbow-announce) and at least one email list on
But no messages to kwlug-disc seem to be affected. What's so
different? Could it be a hostname thing? (kwlug.org vs
lists.wpirg.org?). But then the kwartzlab.ca lists should be okay
too, I think.
Of course, if I respond to this list using the Yahoo! webmail
interface (which I kind of hate) then my messages will go through.
That is why I was asking about mutt; I assumed something in my mail
client was messed up.

This is not the case, I think. But there could be some mailman
configuration setting at work.

I understand the sentiment, but boy does that idea make me grouchy. I
have no great love for Yahoo!, but it has been working "well enough".
There is a lot of inertia involved in switching addresses. Also, I am
a cheapskate, so finding a gratis email provider that is reliable is
difficult and unfair to expect. (I guess my privacy is a small price
to pay for "free" email?)
