Why have you set this? Normally vacation will refuse to respond to a
message which doesn't have your address in one of the recipient header
fields; in fact the standard says that it MUST NOT respond unless this
is the case. This setting turns that check off, in which case Pigeonhole
will send a vacation response (despite the standard) but sends it from
Postmaster. I assume this is done for privacy reasons, since the person
the vacation response is being sent to doesn't necessarily know the user
who set the vacation exists, or what their address might be.

If you send a message with the user's email address in To:, do you get a
vacation response From: the correct address?
