[Arm-netbook] Warning: yahoo users postings might be lost

[Alain Williams]

Summary: email sent by users with mailboxes held by yahoo may have their email disappear.

This may be mail to a mail list (such as this one) their mail list postings may
not be received by other yahoo users and also gmail users & a few others.

Yahoo made changes without warning and have caused a huge on-line discussion by
mailing list operators.

Yahoo broke email lists.

This is because at the start of the week Yahoo changed their DMARC settings to
ask servers that receive a message with a yahoo.com email address in the From:
line to reject it if it isn't properly signed by yahoo, which all messages they
send will be.

Basically, Yahoo has said that it users are not supposed to use any
mailing list configured in the manner that they are often configured in.

There are several possible workarounds, but none of them satisfactory.
Discussion continues.
