Comment (by dmsnell):

 > Semantics, but since I was using sendmail -f to set the envelope sender,
 it is now being overridden via the second -f.

 Thanks for clarifying. It’s a hot topic, so I am trying hard to stick with
 factual statements to avoid triggering different folks. I am led to
 believe that using `-f` in the `sendmail_path` is another one of these
 “invalid but standard” practices, and that it would be much easier for all
 parts of the system to cooperate if the return-path were set via
 `wp_mail_from`.

 In 6.9.1, by the way, WordPress will avoid sending a second `-f` if it
 detects one in `sendmail_path` — that was an oversight when the patch was
 merged into 6.9.
