Sendmail aliases[1] supports expansion to a file ("/path/name") or
pipe ("|command"), as well as file inclusion (":include: /path/name"),
however, our implementation does not support such functionality.

According to the documentation, the parser should print a warning for
any explicitly unsupported constructs.  These are now explicitly
unsupported, so the parser should warn on |, /, and :include: .
Perhaps the lines that match should be ignored like the others, too.

Indeed. I had that in mind and then promptly forgot about it. Here's a
follow-on patch:

Subject: [PATCH 10/9] send-email: further warn about unsupported sendmail aliases features

The sendmail aliases parser diagnoses unsupported features and
unrecognized lines. For completeness, also warn about unsupported
redirection to "/path/name" and "|command", as well as ":include:".
