Meta's emails and Pipelining not supported with smtpd
Hi. I've noticed that verification code from WhatsApp send via email is not arriving to my SMTP server which runs OpenSMTPd on OpenBSD 7.7/amd64. This is what I see in /var/log/maillog: > smtp connected address=69.171.232.141 > host=69-171-232-141.mail-mail.facebook.com > smtp tls ciphers=TLSv1
