Specifically, here's a test from my Yahoo! account to an autism

the email is parsed by mailman, it does not appear to reflect the

smfi_chgfrom only changes the envelope sender. I think Mailman (and
possibly Yahoo?) might be looking at the From: header instead.
Thanks. I think I also need to exempt emails to -owner, etc. Need to
look at that.
With regards to the MIMEDefang list, I don't plan on doing anything
special. If Yahoo wants to break legitimate mailing lists for its
users, that's Yahoo's problem, not mine. Luckily, I do not depend
on being able to reach Yahoo subscribers for my business to be viable,
so... meh.
The article might not be doing a good job of explaining the basic,
real-world issue:
- Yahoo user sends email to list
- List resends email to all members
- All the various recipients that acknowledge p=reject reject the mail
as forged
- You look like a spammer
- Recipient ISPs blacklist you
- Members on some lists (like mailman) are unsubscribed for reaching
bounce thresholds
regards,
KAM
