FWIW, when I tried sending a message to this list without a From field,

Possibly a configuration option... I'd have to check.
It is indeed configurable, controlled typically via an "F"
mailer definition flag which is typically used to indicate
a From (or Resent-From) field requirement in conjunction
with a configuration file header field definition. Removing
the F flag from sendmail's smtp mailer definitions causes the
addition not to happen (at that MTA).
