It's hard to say for sure, but it looks to me like your outbound mail is
being relayed through a mail server at Amazon Web Services, possibly by
US-West and for some reason that server is not accepting these messages.
It don't think it has anything to do with DMARC, but it might.

I think it's more likely some kind of rate limiting or they just don't
like the server that's sending to them.

I think you will have to involve your hosting provider in diagnosing and
fixing this issue. It may be some configuration in their outgoing mail
that is the problem or something else, but without a whole lot more info
than is in those bounce messages, I can't say.

Thanks for the assistance on this.  It appears from the responses, there is
nothing wrong with my mailman setup.   I have noticed I am getting a bunch
of these e-mails.This is all so confusing...just want to scouts in the
troop to be able to send and receive e-mail from the mailing list.   Any
suggestions on how to fix this?

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

Subject: Mailman and dmark help -- please

I have a mailing list setup for our boy scout troop.  The site is running
mailman version version 2.1.18-1.   I looking at various lists, I believe I
have as much set as I can.

(Details for from_is_list) = Munge From

I really -- really want the list set so when someone gets an e-mail from the
list they can see who sent it and when they click reply it goes to the
original sender.  When I have the remove sender option, etc. People don't
know who the e-mail came from or how to directly reply.

I was reading about some DNS DMARC settings, but frankly it really confused
me.  What I have observed:

E-mail from MSN to list
Comcast Users = DOn't Get it
AOL Users = Don't Get it
Yahoo Users = Don't Get it
users with arvixe accounts = Do Get it.

E-mail from GMAIL to list
Comcast Users = DOn't Get it
AOL Users = Don't Get it
Yahoo Users = Don't Get it
users with arvixe accounts = Do Get it.

E-mail from Comcast to list
Comcast Users = DO Get it
AOL Users = Don't Get it
Yahoo Users = Do Get it
outlook.com = Do Get it
users with arvixe accounts = Do Get it.

E-mail from AOL to list
Comcast Users = DO Get it
AOL Users = Don't Get it
Yahoo Users = Dont Get it
outlook.com = Dont Get it
users with arvixe accounts = Do Get it.

E-mail from Outlook to list
Comcast Users = DO Get it
AOL Users = Don't Get it
Yahoo Users = Dont Get it
outlook.com = Dont Get it
users with arvixe accounts = Do Get it.

E-mail from Yahoo to list
Comcast Users = DO Get it
AOL Users = Don't Get it
Yahoo Users = Do Get it
outlook.com = Do Get it
users with arvixe accounts = Do Get it.

Any sugestions?  My site is troop101-wa.org if looking at its DNS records
could help.

Dennis

Sent previously, but inadvertently to the OP only. Much overlap with
Stephen's reply.

While it doesn't really say so, from_is_list should be considered
deprecated. Use Privacy options... -> Sender filters ->
dmarc_moderation_action instead for a less generally disruptive approach.

What remove sender option? Have you set anonymous_list = Yes?

This isn't DMARC. msn.com doesn't publish a DMARC policy.

This isn't DMARC. gmail.com publishes a DMARC p=none policy.

This isn't DMARC. comcast.net publishes a DMARC p=none policy. Also,
only AOL doesn't like it.

aol.com publishes DMARC p=reject. Comcast honors that policy, so
whatever DMARC mitigation policy is in effect seems to be working in
this case.

See AOL above. The same things apply to yahoo.com.

I see you do have an SPF record which is good in general, but won't help
with DMARC. You might also consider DKIM signing your outgoing mail
which also will help in general but not with DMARC.

You clearly have deliverability issues, but they don't seem to be DMARC
related.

Also, simple From: munging for DMARC should preserve the From: display
name or list member's 'real name' in the resulting From: John Doe via
list  header and put the original From: data in
Reply-To: so with an RFC compliant MUA, 'reply' will go to the original
From: and 'reply all' will go to the original From: and the list.

What are your settings for General Options ->
 from_is_list
 anonymous_list
 first_strip_reply_to
 reply_goes_to_list
 reply_to_address

For your deliverability, you need to see the server's outgoing MTA logs
to see if any of the undelivered mail is rejected at SMTP time and why
and also look at Mailman's bounce log to see if mail is otherwise
bouncing. You probably have to get your hosting provider to do this if
you can. See .

Also see  for some general information
on deliverability.
