Check this by looking at your syslog or maillog, for an outgoing message from <> to the hotmail address. It will be within seconds of the incoming message from the hotmail address. Actual delivery to the hotmail inbox is not your concern, and from stories I've heard, don't count on it to work. The hotmail user may have a user-level configuration that throws the mail away, without realizing it. If there are any other rules in the sieve filter before the vacation rule, check whether they say to stop. For example, if I say put mail from foo@xxxxxxxxxxx in inbox and stop, and then have the vacation rule after that, foo@xxxxxxxxxxx won't get the vacation message. You know of course that vacation replies per sender only once a day, or some longer period, right? Just checking.
