Hi List,

I have a brand new domain I purchased for a customer back in July, it’s
never even had a dns entry associated with it until a few weeks ago. We
recently setup their new email addresses and was doing some
troubleshooting when I noticed a large amount of spam being sent to an
invalid address.

Considering it is most likely 100% spam, is there any way I can auto
bounce these to someone here to get them added to the signatures?

I don't believe this type of spam is well suited to sane security. If you're using a qmail based MTA, I highly recommend using http://spamdyke.org/. It's very effective at reducing spam, and will reduce the load on your host at the same time. spamdyke is amazing.
In comparison, Postfix has or will have (2.8 series' postscreen) many of these features as well.
A good reject defense that suites *your* environment will keep the spam down.
