A normal vacation response message is sent to nearly all incoming messages (or to any message in your Contacts list), which is not what is desired in this situation. You could try to write custom Sieve to only respond to one sender domain, but then the normal vacation feature wouldn't work cleanly. In addition, the vacation response does not indicate to an Outlook Exchange sending system that there is any problem with the address.See below for more details.

When you use the two different systems (vacation or sieve reject) here are the differences in what is returned to an Outlook Exchange sender:
Code:
Message field     Vacation                  Sieve reject
--------------------------------------------------------------------------
From:             Fastmail address          Mail Sieve Subsystem
Icon:             <none>                    <Message deleted without being read notice icon>
Subject:          Auto: <original subject>  Not read: <original subject>
Message body:     <exact text>              Sieve rejection message (see below)
The Sieve rejection message body appears as follows in Outlook:
Code:
Your message was automatically rejected by Sieve, a mail
filtering language.

The following reason was given:

<exact text in your Sieve rule>
In my opinion the Sieve reject response makes it much more obvious to an Outlook Exchange sender that something went wrong and they shouldn't be using that address.
