Sometimes the Received lines carry the To envelope address as in:
Received from (blah) by (blah) for <user@domain.com>
... and sometimes they don't.
I know it's governed by the Header Format .cf definition (in my sendmail.cf):
$?u for $u;
... but I'm not clear why the $u macro should be undefined in some cases, or whether I'd be better switching it to $: (or $h?) instead.
