### 3.13 lmtpd ¶

The LMTP is a local mail transport protocol defined in RFC 2033. GNU Mailutils is shipped with `lmtpd` - a daemon for delivering messages using this protocol.

The daemon shares most of its codebase and configuration with `mda` and consequently provides the same features. See mda, for a detailed description of these.

The behavior of `lmtpd` is affected by the following configuration statements:
