There are two things going on here. I don't know exactly how they are
related. But I know that they are.

1. Something in Yahoo's new DMARC policy is breaking email sent from
mailing lists. It apparently affects *all* mailing lists, not just PDML.

For Gmail users it shows up as a tag of some kind that causes Gmail to
push the messages into the user's SPAM folder.

For YAHOO USERS, the messages from PDML go straight into the bit bucket.
It doesn't go into the SPAM folder; it doesn't get a bounce message (as
far as I can tell) ... it just disappears.

But, I'm not even getting that far.

2. I have a separate problem with Yahoo.

I pay for Yahoo Mail Plus so that I can use Thunderbird with Yahoo's POP
& SMTP servers and not have to log into WebMail. I *HATE* WebMail.

For the last several days whenever I try to send email from my Yahoo
account using Thunderbird, I get an error message from Thunderbird:

Login Failed
Login to server smtp.mail.yahoo.com failed
[Retry] [Enter New Password] [Cancel]

If I click [Retry] or [Enter New Password] and enter my Yahoo password
it will restart the timer and after the timeout it will return to "Login
Failed" again.

If I select [Cancel] it just sits there churning endlessly waiting for
the SMTP server.

After much digging I found an 800 number for Yahoo "customer care".
Remember I *PAY* for Yahoo Mail Plus.

When I called the 800 number I got a voice response unit that directed
me to a certain web address, where I'm supposed to click a link to send
them an email. When I clicked the link, it displayed a message directing
me to call the 800 number.

It's starting to PISS ME OFF!

Here's another article discussing this Yahoo change. It suggests that
there's a fix that email list operators may be able to implement
fairly easily, depending on the list software in use of course.

I have no idea if Doug can do anything about the PDML list though. (It
runs on GNU Mailman)

Just in case:
If you are concerned about e-mails that you are sending to PDML from
your Yahoo account via Yahoo smtp servers, than the recent change
described in the links posted by Matthew should not affect you.

It affects only Yahoo users who are sending e-mail via smtp servers
OTHER than those from Yahoo.

(The second link's post explains how to fix the problem:
"Endusers can do a couple things. For one-to-one mail make sure you're
using the Yahoo outgoing mail servers and that should fix the problem
without you having to really make any change." )


The Yahoo change does affect him, in the sense that his emails to the
PDML will be marked as spam for those of us who receive them on Gmail
and certain other providers.

John uses Yahoo's SMTP servers to send mail to the PDML. The PDML mail
server sends John's mail (with a Yahoo "From" address) to my Gmail
account (and everyone else on the list). Gmail sees the mail with
John's Yahoo "From" address, but it didn't come from Yahoo's SMTP
server--it came from the PDML mail server. Gmail, as requested by
Yahoo's DMARC records, marks that message as spam.

Basically, people with Yahoo addresses can't participate effectively
on mailing lists anymore.

So, what on earth is Yahoo's justification for this?  Some sort of security
issue?

To the uninformed masses (me included), it just seems nuts.

It's a misguided (and misfiring) attempt by Yahoo to cut down on spam.
Yes, it's nuts. They don't call 'em Yahoo! for nothing.

http://www.computerworld.com/s/article/9247512/Yahoo_email_anti_spoofing_policy_breaks_mailing_lists

Anyone sending mail from a Yahoo account to the PDML should go get
another email account, not on Yahoo, and use that for PDML mail. Until
Yahoo smartens up, or forever, whichever is shorter.

The other fix is for _everyone_ to install an email filter that
exempts all PDML mail from spam filtering. Unhappily, that is doomed
as lots of folks don't know how and filters can have annoying
side-effects (like in Gmail).
