"first.last@example.com", address.user will evaluate as "first.last".

Quoted Local Part
Since: Version 2026.04.09-ea3b2a9b
The functionality described in this section requires version 2026.04.09-ea3b2a9b of KumoMTA, or a more recent version.
Prior releases of KumoMTA had inconsistent behavior around handling envelope
addresses whose local part was a quoted string. The behavior has been improved,
and this user field will now return the normalized local part from the address.
Normalization removes any quoting and quotes from the local part.
Some examples of how this works are shown in the table below:
| Address | Normalized Local Part |
|---|---|
foo@example.com |
foo |
"foo"@example.com |
foo |
"f\oo"@example.com |
foo |
"info@"@example.com |
info@ |
