I'm facing a new problem with WordPress user registration on a site.
/usr/sbin/sendmail is used to send users a generated password via email.
this (https://github.com/PHPMailer/PHPMailer/issues/1059) link suggests (by its answer) that a "certificate" may be needed.
I think it means an SSL certificate. I think maybe I need to set up https on my account, and buy a certificate these days anyway, but is there a recent change in your infrastructure to cause this to break? I'm finding I'm at a loss. below is debug output:
