"Precedence: bulk" indicates that the e-mail is either from a mailing list or somehow autogenerated (like an autoreply). It is almost always a good idea to filter those out from any automated e-mail handling, so yes, do go ahead.

There's a very important nuance here. Replying to them is bad. Dropping them on the floor is even worse. Just because mail has been proxied by an automated system doesn't mean it's junk.

We ran into this problem a few weeks ago. One of our RT systems is addressed via a publicly advertised campus email address that had been implemented as a majordomo list(*). Mail generated by such lists uses 'Precedence: bulk' headers, so AutoReplies weren't being sent back to the Requestors.

It took me a while to figure out what was going on, especially since AutoReply had been working before when a different RT mailing address was used, during testing. We ended up changing from a majordomo list to a simple mail forwarder(*).

I briefly contemplated changing RT to remove 'Precedence: bulk' from the list of headers that RT considers as belonging to mail that shouldn't be replied to. But, for reasons implied by Jesse's comments (though with a different slant), I didn't want to take such a rash action that would fly in the face of standard mail header usage.

(*) It was first set up as a majordomo list because the self-service web page provided by the campus central mail server administrators no longer allows setting up of simple mail forwarders (because of spam issues). Once this problem with RT was discovered, special arrangements were made with the server administrators to get a simple list created for this purpose.
