Your smarthost entry isn't being ignored, but anything which can be
delivered locally will take priority over that setting.
You'll either need to remove localhost and so forth from class w
(which sometimes involves hostnames in /etc/mail/local-host-names),
or require sendmail to canonify unqualified usernames with a non-
local hostname like "user at mail.domain.com". Look into the
MASQUERADE_AS() feature, and possibly always_add_domain,
allmasquerade, and/or masquerade_entire_domain.

Barring anti-spam measures, MTAs don't care about whether the
contents of an email are HTML.
