I second this. I’ve told our clients that they should not expect any communications to and from Yahoo accounts.

In  my experience Yahoo has a lot to answer for their weak security, spammy mail accounts and dodgy spam history..

They are the last company to be bleating on about  security given their poor track record.

Personally, watermarks stops backscatter and allows for NDRs to be handled more efficiently.

If the price paid for that is not being able to email Yahoo, then  so be it.
