Smtp 554 Message Looks Like Spam Why Does Mail To Owners Of Yahoo! Groups Keep Bouncing?

Why does mail to owners of Yahoo! Groups keep bouncing? - smtp 554 message looks like spam

I tried the moderators of the two different groups that I meet, contact

Every time I try, I get the same answer.

And no, it was none of the emails I have tried to sendAnd the Bcc field.
A simple garden variety "a \\ \\ \\ \\ \\ \\ \\ \\ u0026lt; XXXXX-owner@yahoogroups.com>

Any message sent to all persons, including the groups themselves are very good.
This strange behavior when sending messages to the owners.
