The vacation action requires that the mail explicitly lists the 
recipient in the To/Cc/etc headers of the message. Your test message 
does not contain the user's address in the To: header.

 From RFC 5230:

====
4.5.  Address Parameter and Limiting Replies to Personal Messages

"Vacation" MUST NOT respond to a message unless the recipient user's
email address is in a "To", "Cc", "Bcc", "Resent-To", "Resent-Cc", or
"Resent-Bcc" line of the original message.  An email address is
considered to belong to the recipient if it is one of:

1.  an email address known by the implementation to be associated
     with the recipient,

2.  the final envelope recipient address if it's available to the
     implementation, or

3.  an address specified by the script writer via the ":addresses"
     argument described in the next paragraph.

Users can supply additional mail addresses that are theirs with the
":addresses" argument, which takes a string-list listing additional
addresses that a user might have.  These addresses are considered to
belong to the recipient user in addition to the addresses known to
the implementation.

Hence, you get the above log message, indicating no vacation response is 
sent.
