= Local Mail Transfer Protocol (LMTP)
:navtitle: LMTP
== Overview
https://en.wikipedia.org/wiki/Local_Mail_Transfer_Protocol[Local Mail Transfer Protocol] ("LMTP")
is
From <<RFC2033>>:
Although LMTP is an alternative protocol to ESMTP, it uses (with a
few changes) the syntax and semantics of ESMTP. This design permits
LMTP to utilize the extensions defined for ESMTP. LMTP should be
used only by specific prior arrangement and configuration, and it
MUST NOT be used on TCP port 25.
== Specifications
=== RFC2033
https://tools.ietf.org/html/rfc2033[RFC2033] ("Local Mail Transfer Protocol") was published
in 1996, and defines a simplified protocol for local mail delivery mainly inspired by
xref:protocols/esmtp.adoc[ESMTP]. It is the first, last, and only specification of its kind.
