If the address header consists of a single simple address, returns the mailbox
portion of the address. For example, if the address is
"first.last@example.com", addressheader.domain will evaluate as
"first.last".
If the address header is not a single simple address, raises an error.
See also addressheader.domain, addressheader.name.
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 user field now returns the normalized/decoded local part. Previously,
quoted local parts such as "quoted"@example.com were returned with the
RFC 5322 quoting intact (e.g. "quoted"); they now return the decoded
semantic value (e.g. quoted). The same applies to entries in
addressheader.list.
