Hello,
I am running OpenBSD 6.5 with OpenSMTPD and dovecot and if I send an email to
an invalid email address, I do not get a bounce back from OpenSMTPD telling me
that the email address is invalid. So this means I never know that I made a
mistake in sending my email.
I have the same problem (my logs look the same) and are very interested
in a solution.
