id
Note
This is a field rather than a method, so you must use mimepart.id
rather than mimepart:id to reference it.
Since: Dev Builds Only
The functionality described in this section requires a dev build of KumoMTA. You can obtain a dev build by following the instructions in the Installation section.
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.
