You're talking about a Sendmail compatibility feature from 20 years
ago. According to a contemporary Sendmail manual, the From: header
format was commonly defined as either "$?x$x <$g>$|$g$." or "g$?x
($x)$.", corresponding to the following two formats:
Eric Allman <e...@cs.berkeley.edu>
e...@cs.berkeley.edu (Eric Allman)
(that's a quote from sendmail 8.9.0 from 1998).
Your complaint illustrates that there are still programs that create
email without a From: header.
I suppose I will eventually change the code, but email header syntax
is delicate stuff.

That must be part of an obsolete fake mail detection scheme. The
idea was that if I never send mail as ``From: name <address>'',
then all mail that contains that specific form is a fake.
