[DeTomaso] [NPC] Why email is failing for Yahoo, AOL, Gmail, and probably a bunch of others.

[Asa Jay Laughton]

   I originally wrote this in response to a clarification from Mike Drew
   regarding posts not getting to his AOL account.  He asserted the
   Mailman software was making changes to the emails from AOL sources so
   that AOL was rejecting them.  Well... he's partially right.
   The Mailman software does not screen incoming emails to see if they are
   from AOL and do something different with them.  It treats all incoming
   email the same way.
   AOL on the other hand..... is beginning to live up to the moniker of
   AOHell.  You'll need to read to the end to understand.
   Investigating why things are broken could honestly and easily take an
   administrator down a very long rabbit hole.  Nothing has changed as far
   as I'm aware, with the Mailman system on the POCA server.  Something
   would have to have changed on AOL.  Like..... they did something to
   mitigate the recent Heartbleed bug and it's now causing problems with
   mail delivery from Mailman.  The timing is about right.
   Let's take a trip down that rabbit hole for just a short distance; make
   sure to tie a rope to your waist and have somebody pull you back up.
   For an older answer to why AOL rejects messages, you can start here:
   [1]http://wiki.list.org/pages/viewpage.action?pageId=4030690
   That page leads you to AOL's post master site where the rabbit hole has
   the opportunity to grow longer:

   Now, an administrator (someone other than -me-) could conceivable jump
   through all the hoops to try and get an email feedback loop started
   with AOL, try to get whitelisted, etc. but as it says in their terms
   and conditions, it might not even make a difference if even just one
   person clicks on "this email is spam."
   But let's investigate this further to see if Mailman is the real
   culprit.
   The information in the next link, indicates a change was recently made
   at Yahoo, and begins to explain why Mailman is getting a crapload of
   bounces from Yahoo which end up disabling accounts:

   That information probably applies to AOL as indicated near the bottom
   of the post where it says it's not limited to just Yahoo.  So let's
   keep searching.
   You can read more about the Yahoo problem here:

   cy-breaks-mailing-lists.html
   Aha, now we are getting close, this one talks specifically about AOL:

   ... and links directly to this blog post -by- AOL:
   [6]http://postmaster-blog.aol.com/2014/04/22/aol-mail-updates-dmarc-pol
   icy-to-reject/
   Here is another summary of the problem with both AOL and Yahoo:
   [7]http://blog.madmimi.com/yahoo-dmarc-changes-email-marketing/
   I can find no information on potential changes for Mailman to mitigate
   this.
   All of which indicates.... it's an AOL problem; not one that Mailman
   induced.  There is no fix in Mailman for this.  I'm not spending any
   more time researching something that can't be fixed in Mailman, and can
   only be fixed on the ISP side.

     Maybe it's AOL filtering them?  I can't say.

     >>>I phrased it wrong.  The forum is somehow 'polluting' posts from
     AOL sources, so that AOL itself filters them out, and other ISPs
     automatically send them to the user's spam folders.
