Subject[Csound] Admin:problem with Yahoo mail
There is a (potential) problem with yahoo subscribers, described
below.  So far I have resisted the "solution" to unsubscribe all such,
but have taken what I hope will be a workable scheme (involving more in
work...)

Now only to work out why free.fr and some others think it is all
spam...

========================================================================
Problem:

On April 4th, 2014 Yahoo updated the DMARC  record with "p=reject" for
the "yahoo.com" domain. This was done to proactively by Yahoo to
protect their users from increasing email spam that uses Yahoo email
addresses from other mail servers.  On April 22nd AOL similarly
updated it's DMARC record with "p=reject" for the "aol.com" 

All DMARC compliant mail receivers (including Yahoo, Hotmail, and
Gmail) are now bouncing emails sent as "@yahoo.com"  and "@aol.com"
addresses that aren't sent through Yahoo servers or AOL servers. Any
messages without a proper Domain Keys Identified Mail (DKIM) signature
or Sender Policy Framework (SPF) alignment will be rejected. 

How this impacts Listserv:

A subscriber/list member from *@yahoo.com or *@aol.com posts a message
(or a replies to a message) to your list.  This will go to some
subscribers, but will NOT go to subscribers/list members at yahoo.com.
Messages to this domain will not only not be delivered but will be
bounced/refused as if the recipients at those domains do not exist.
Thus, after a few such messages, your subscribers/list members at all
of those problematic domains are at risk to be auto-deleted from your
list(s).

Resolution:

At this point there is no easy resolution to this issue.  L-Soft (the
vendor that created Listserv) is working on a patch to correct the
issue, but it won't be available soon, as it will be a server upgrade,
so it has to be tested before it's released.
