Few mails from IP xxx.xxx.xxx.xx were getting rejected from one of

Don't munge Reply-To: ;)
It seems to me that since dmarc munging adds the senders address to the
reply-to header, if a user receives a copy of their own postings this is
the result.
No. Based on AOL's reply above, this has nothing to do with DMARC. If
you set reply_goes_to_list to This list (note that Poster is the
/strongly/ recommended setting) both the To: and Reply-To: headers of
outgoing messages will contain the list address.
However, it seems that this means AOL will not accept mail from any list
with reply_goes_to_list = This list, and since this is a common,
although not recommended, configuration, if this is the case, it seems
there should be much more reports of this issue, and I haven't seen that.
Can anyone else confirm that this has happened to them and if so what
else can someone do except to wrap the message from senders that
implement dmarc rejection as in dmarc_moderation_action?
Even if this is a DMARC issue, Wrap message won't change it because the
headers in the wrapper will be the same as those in a Munge from message.
Is there a recommended policy regarding this issue?
Set reply_goes_to_list to Poster
--
I'm running mailman version 2.1.22.
reply_goes_to_list is set to poster
from_is_list is set to "Munge From".
Documentation describes "Munge From" to be
"This action replaces the poster's address in the From: header with the
list's posting address and adds the poster's address to the addresses in
the original Reply-To: header."
This means that messages with a munged From: header should pass dmarc
checks but the senders address will be added to the reply-to header. Does
this not mean that the Reply-To: and the To: address will be the same for
some users?
