Sidestepping your final question, your immediate fix is to return to
sendmail by restoring your /etc/mail/mailer.conf to use sendmail by
changing the dma references back to "/usr/libexec/sendmail/sendmail".
We were all warned about this in /usr/src/UPDATING entry 20221205,
but that was a long time ago, and it bit me only just now when I was
updating from 13.4-RELEASE to 13.2-RELEASE and too quickly accepted
what etcupdate gave me on /etc/mail/mailer.conf.           -- George
