No. The smtpd_xxx parameters are for RECEIVING email.
The LMTP protocol is for DELIVERING email.
No. That text covers RECEIVING email. LMTP is for DELVERING email.
Maybe im over stating the obvious, but i can see how there could be some
ambiguity mentioned here.
In this context saying that LMTP is for delivering mail, just to
clarify, it's not delivering mail like you are sending out an email from
you to another service (like from y...@nasa.gov to some...@gmail.com)
although with some tweaking you could.
But delivering in the sense that the email just received by postfix is
being delivered to the users mail box.
