id

local id = mimepart.id

Note

This is a field rather than a method, so you must use mimepart.id rather than mimepart:id to reference it.

Since: Version 2025.10.06-5ec871ab

The functionality described in this section requires version 2025.10.06-5ec871ab of KumoMTA, or a more recent version.

The id field represents the position of the part within the mime tree at the time that it was parsed from its containing message.

This has very limited use at the current time.
