Do any current email clients implement handling of the "Expires" email header (RFC 4021 https://tools.ietf.org/html/rfc4021#section-2.1.49)? By handling of, I mean automatic (optional) deleting of expired messages as well as user interface to setting an expiry date on outgoing email.

Microsoft Outlook (versions Outlook for Office 365, Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010) allows setting of expiry date on outgoing email.
Microsoft Office Reference: Set a message expiration date
The Outlook client does not include a way to auto-delete expired messages, but it does display them with strikethrough font modifier.
