Every Unix mail client I'm aware of that uses /usr/lib/sendmail or the
equivalent as the mail sending interface passes Bcc to it and expects it
to deal with it. qmail-header(5) says:
Every message must contain at least one To or Cc or Bcc.
qmail-inject deletes any Bcc field.
So it's not quite true that *all* MUAs must concern themselves with this.
Of course, the original question probably concerned an MUA that thought it
could speak SMTP to a mail server when it actually wasn't speaking SMTP at
all (it probably also expects unqualified addresses to work). The
solution may be to run ofmipd for such clients, from the mess822 package.
