Nope.

You're right.  I checked here and heirloom-mailx does a `sendmail -i'
and leaves that to add a `From:'.

Yep, and I followed that path too.  :-)
http://sources.debian.net/src/postfix/2.11.1-1/src/cleanup/cleanup_message.c?hl=686:692#L676
And I use Postfix.

I had a quick look at Exim, and I think it uses <>.
http://sources.debian.net/src/exim4/4.84%7ERC1-3/src/receive.c?hl=2126:2127#L2105
and various other places.  Postfix is very common though.
