[TowerTalk] Bounces

Here is what I received from a reflector administrator yesterday....

Yahoo introduced a feature (DMARC) this week that basically says "If a
message has a yahoo.com email address as the FROM address, and it didn't
come from a Yahoo.com server, then it's not acceptable."

This policy is not compatible with mailing lists.  List messages all go out
with the email address of the person that posted the message.  If the
person posting is using an @yahoo.com email address, the message goes out
with FROM: xxxx at yahoo.com.  This message is sent from the mailing list
server  and not from Yahoo.com's servers...
therefore Yahoo is not accepting these messages.

It's a little complicated, but this policy is also causing other members to
get unsubscribed due to bounces.  Other providers are now bouncing these
messages, because Yahoo has basically instructed them to do so.  You may
have already received some mail from our list, asking you to reconfirm your
subscription.  It is because of this issue, caused by yahoo.com users
posting to our list.

You can read more about it here:
And here: http://www.ietf.org/mail-archive/web/ietf/current/msg87153.html

The second link suggests that to fix this problem we need to:

* Suspend posting permission of all yahoo.com addresses, to limit damage.
* Tell Yahoo users to get a new mail account somewhere else, pronto, if
they want to continue using mailing lists.

I am going to ask the Board to consider these options.  This email is
mainly a heads up to yahoo.com email users that changes are a brewing and
you should be looking into other options for your mailing list mail.

One idea for yahoo.com users:  Consider using a free email forwarder from
arrl.net  and have it forward to your yahoo.com address.
Subscribe to the  list with your arrl.net  address, then
configure your email program to send from your arrl. email
address when you post to the (and other) mailing list.  Another idea
would be to move to a different free email provider, such as GMail.
