[Mailman-Users] Mailman and dmark help -- please

[Dennis Longnecker]

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.
