The question that no one seems to be able to answer is whether the spambots would then get the new address from the autoreply.
In my opinion it shall be presupposed that eventually some spammer will harvest such email address.
Collecting new fresh email addresses is the very basis of successful spamming practice, and collecting them from auto-replies is a no-brainer, run a script that takes few seconds that's it.
However the chances are not that big as they seem, because spammers use fake email addresses, or addresses of other innocent spam victims, thus like 99+% of your auto-replies will not end on spammer's server.
So again I'd be surprised if some spammer didn't use this method to collect fresh email addresses, but how big or small the chances are I don't know.
I didn't test antispam tools in years, but one I can recommend is SpamBayes. More people (incl. my experience) reported that after some training SpamBayes reports no false positives, which means you can empty Junk Mail folder without an eye blink = tremendous time saver.
So if you are looking for dedicated antispam software, I'd look for the one that has reputation for no false positives after some training. It's easier to spot and delete 5 spams from Inbox every day, than it is to go through 400+ spams every day just to spot that one occasional false positive.
