Yes, sendmail assumes that the domain name is not needed for the
envelope recipient for local delivery.

Yes, when I was debugging this, I found that CCing the message to
user at unspecified-domain would cause vacation to work!

I'm using a similar set of patches.  I did submit them to the Cyrus

Sendmail can rewrite header addresses for local delivery.  This works
well.  It's only the envelope recipient that has the domain stripped.
