OK, so I tested again and the [smtp] block is a red herring - it's being
ignored and things are falling back to msmtp instead these days.  The
configuration block is:

	[sendemail]
        smtpServer = mail.kernel.org
        smtpServerPort = 587
        smtpEncryption = tls
        smtpUser = = broonie
        smtpPass = XXXXXXXXXXXXX
        from = broonie@kernel.org

which seems to match both the manpage and

	https://korg.docs.kernel.org/mail.html

AFAICT (I've used both smtpuser and smtpUser type LHSs).
